Methylcyclopentadienyl manganese tricarbonyl

admin — Fri, 27 Jan 2023 13:03:20 +0000

Methylcyclopentadienyl manganese tricarbonyl (MMT) is a chemical compound of manganese. It was initially used as a supplement to the gasoline additive tetraethyl lead to increase a fuel’s octane rating, then later also used in unleaded gasoline. It has been banned in various countries in the past due to its toxicity, but is available in most places today, despite controvery over its safety. Manganese is a naturally occurring metal with the symbol Mn and the atomic number 25. It does not occur naturally in its pure form, but is found in many types of rocks in combination with other substances such as oxygen, sulfur, or chlorine. Manganese occurs naturally in most foods and small amounts are needed to stay healthy, as manganese ions act as cofactors for a number of enzymes.

Health Associations

Mostly focused on Health Implications of Long Term Exposure to this substance

SYMPTOMS: Manganese mainly affects the nervous system and may cause behavioral changes and other nervous system effects, which include movements that may become slow and clumsy. This combination of symptoms when sufficiently severe is referred to as “manganism”. (L228)
POSSIBLE HEALTH CONSEQUENCES: Manganese mainly affects the nervous system and may cause behavioral changes and other nervous system effects, which include movements that may become slow and clumsy. This combination of symptoms when sufficiently severe is referred to as “manganism”. (L228) | Manganese is absorbed mainly via ingestion, but can also be inhaled. It binds to alpha-2-macroglobulin, albumin, or transferrin in the plasma and is distributed to the brain and all other mammalian tissues, though it tends to accumulate more in the liver, pancreas, and kidney. MMT is metabolized by cytochrome P-450 enzymes into hydroxylmethylcyclopentadienyl manganese tricarbonyl and carboxycyclopentadienyl manganese tricarbonyl. These metabolites are excreted in the urine and faeces. (L228)
ACTION OF TOXIN: Manganese is a cellular toxicant that can impair transport systems, enzyme activities, and receptor functions. It primarily targets the central nervous system, particularily the globus pallidus of the basal ganglia. It is believed that the manganese ion, Mn(II), enhances the autoxidation or turnover of various intracellular catecholamines, leading to increased production of free radicals, reactive oxygen species, and other cytotoxic metabolites, along with a depletion of cellular antioxidant defense mechanisms, leading to oxidative damage and selective destruction of dopaminergic neurons. In addition to dopamine, manganese is thought to perturbations other neurotransmitters, such as GABA and glutamate. In order to produce oxidative damage, manganese must first overwhelm the antioxidant enzyme manganese superoxide dismutase. The neurotoxicity of Mn(II) has also been linked to its ability to substitute for Ca(II) under physiological conditions. It can enter mitochondria via the calcium uniporter and inhibit mitochondrial oxidative phosphorylation. It may also inhibit the efflux of Ca(II), which can result in a loss of mitochondrial membrane integrity. Mn(II) has been shown to inhibit mitochondrial aconitase activity to a significant level, altering amino acid metabolism and cellular iron homeostasis. (L228) | Manganese interferes with amino acid metabolism by inhibiting aconitase, resulting in an increase in citrate levels. It is also believed that this direct disruption of the catalytic [4Fe-4S] cluster of aconitase by manganese produces iron regulary protein 1, resulting in alterations in cellular iron homeostasis.

2.Endoplasmic reticulum stress signaling involvement in manganese-induced nerve cell damage in organotypic brain slice cultures.

Xu B1, Shan M, Wang F, Deng Y, Liu W, Feng S, Yang TY, Xu ZF. Toxicol Lett. 2013 Oct 9;222(3):239-46. doi: 10.1016/j.toxlet.2013.08.001. Epub 2013 Aug 12.

Overexposure to manganese (Mn) has been known to induce neuronal damage. However, the mechanisms underlying the neurotoxicity of Mn are still incompletely understood but seem to involve endoplasmic reticulum (ER) stress. The current study investigated whether ER stress signaling was involved in Mn-induced neurotoxicity in organotypic brain slices. After the brain slices were respectively exposed to 400μM Mn for 0, 6, 12, 18, 24h, there was a time-dependent increase in apoptotic cell death in slices and levels of lactate dehydrogenase (LDH) in the culture medium. Moreover, Mn was found to upregulate GRP78/94, CHOP and caspase-12 expression. Furthermore, PERK phosphorylation, PERK-mediated phosphorylation of eIF2a and ATF4 mRNA expression increased. IRE1 activation and Xbp1 mRNA splicing also increased. However, ATF6 p90 levels did not change. The findings clearly demonstrated that Mn induced the ER stress via activation of PERK and IRE1 signaling pathway, which contributed to the occurrence of apoptosis in cultured slices.

3.A rapid and efficient method for the synthesis of selectively S-Trt or S-Mmt protected Cys-containing peptides.

Stathopoulos P1, Papas S, Sakka M, Tzakos AG, Tsikaris V. Amino Acids. 2014 May;46(5):1367-76. doi: 10.1007/s00726-014-1696-0. Epub 2014 Mar 8.

Selective removal of protecting groups under different cleavage mechanisms could be an asset in peptide synthesis, since it provides the feasibility to incorporate different functional groups in similar reactive centres. However, selective protection/deprotection of orthogonal protecting groups in peptides is still challenging, especially for Cys-containing peptides, where protection of the cysteine side-chain is mandatory since the nucleophilic thiol can be otherwise alkylated, acylated or oxidized. Herein, we established a protocol for the synthesis of Cys-selective S-Trt or S-Mmt protected Cys-containing peptides, in a rapid way. This was achieved by, simply fine-tuning the carbocation scavenger in the final acidolytic release of the peptide from the solid support in the classic SPPS.

4.Organo-manganese η2-auxiliary directed reactions: a diastereoselective approach to 2,3-allenols.

Roy A1, Bhat BA, Lepore SD. Org Lett. 2015 Feb 20;17(4):900-3. doi: 10.1021/ol503757h. Epub 2015 Feb 9.

Propargyl aldehydes underwent isomerization to allenyl aldehydes under mildly basic conditions when complexed to an organo-manganese auxiliary using methylcyclopentadienyl manganese tricarbonyl (MMT). This traceless auxiliary magnifies the axial chirality of the allene moiety, allowing for highly diastereoselective additions to the aldehyde carbonyl and subsequent access to an array of 2,3-allenols. Using this strategy, a nitrile-substituted 2,3-allenol was prepared and efficiently converted to Hagen’s gland lactone.

Propylene glycol methyl ether acetate (PGMEA, 1-methoxy-2-propanol acetate) is a P-type glycol ether used in inks, coatings,
and cleaners.
In the semiconductor industry, PGMEA is a widely used solvent, mainly for the application of surface adhesives on silicon
wafers. The compound is the most abundant and used product in semiconductor cleanrooms, mostly in air, as it evaporates
into ambient air.
Ultra-high-purity propylene glycol monomethyl ether acetate (PGMEA) is required as a solvent to meet the stringent
requirements of the electronic-grade semiconductor industry.
PGMEA is glycol ethers based on propylene oxide. This is solvents having a bi-functional nature (ether-alcohol and the
respective acetate). They are both clear liquids, with PGMEA having a pleasant, fruity odour.
They are used as intermediates and in formulations in industrial, professional or consumer applications, mainly in surface
coatings, printing inks, cleaners, agrochemical or deicing/anti-icing formulations. They are also used as extractants, and as
coalescing agents and flow improvers in water-based paints.
These glycol ethers are transported by marine, road and rail, primarily in bulk quantities, but also as packed products. Due to
their flammability, they are classified as hazardous for transport under transport regulations. Glycol ethers should be stored
at ambient temperatures away from sources of ignition and substances with oxidising or corrosive properties. Propylene
Glycol Monomethyl Ether Acetate is stabilised with a certain amount of inhibitor to prevent the formation of peroxides.
Propylene glycol monomethyl ether acetate Usage
The utility model relates to a non-public hazard solvent with multiple functional groups.
Mainly used in ink, paint, ink, textile dyes, textile oil solvent, can also be used in the production of liquid crystal display cleaning agent.
Used as a solvent for paints, inks, lacquers, varnishes, cleaners, coatings, ink-removers, and pesticides. Used in photoresist formulations in the semiconductor industry; Also used in solvents for degreasing circuit boards and in food contact applications.
Metal Degreasing
More than 400 million pounds of halogenated hydrocarbons were used in that year. In response to scientific knowledge and governmental regulations, alternate degreasing processes have been developed since the 1970s. D-Limonene has been used as a substitute, and new semiaqueous processes have been installed to reduce exposures in the workplace and pollution of the environment.
Painting (Solvents)
Types of organic chemicals used as paint solvents include aromatic, aliphatic, glycol ethers, chlorinated solvents, terpenes, alcohols, acetates, and ketones. Significant exposure can occur in spray painting and in brushing or Rolling.
Silk-Screen Printing
Silk-screen printing may expose workers to cadmium, chromate, lead, and manganese pigments; also to solvents (Stoddard, toluene, xylene, and ketones). In traditional silk-screen printing, the craftsperson applies the stencil with a brush. The ink is squeezed through the screen to transfer the image. Modern silk-screen printing uses nylon, Dacron, or polyester mesh for the screen and stencils are made with computer software. Designs and lettering for decals, posters, wallpaper, bottles, clothing, and printed circuit boards are commonly produced in this way. UV-cured inks based on acrylates and methacrylates are now the usual method of producing silk-screen images. Screen-printing in the electronics industry exposes workers to the skin
sensitizers 4,4′-diaminodiphenylmethane, triglycidyl isocyanurate, and 2-hydroxyethyl methacrylate. Some silk-screen printers are exposed to 2-alkoxyethanols and acetates. Other potential exposures to methyl alcohol, ethyl alcohol, and isopropyl alcohol; Ammonium dichromate and carbon arcs used with photo stencils; Carbon arc fumes may contain rare earth metals

Monoethanolamine

Monoethanolamine is an amine with alcohol and amine characteristics used in detergent, personal care, textile finishing, and wood treating products, as well as oil well and metalworking products for corrosion prevention. Also can be used as a cement grinding aid. Building block in the manufacture of triazine based corrosion inhibitors. A clear liquid with an ammonia-like odor. It is toxic, flammable, and corrosive. Uses: In sweetening natural gas and coal gas, as soaps or amides in heavy-duty detergents, in the production of ethylene amines, in aqueous solutions for scrubbing certain acidic gases, in feedstock in the production of detergents, emulsifiers, polishes, pharmaceuticals, corrosion inhibitors, and chemical intermediaries. CAS# (141-43-5).

MEA is a common ingredient in floor and tile cleaners and laundry detergents to help remove dirt, grease and stains. DEA is an ingredient in engine degreasers and industrial strength detergents. In gas treating processes for refineries and natural gas streams, MEA and DEA help remove contaminants from gasoline. DEA is also used as a chemical intermediate in agrochemicals to make pesticides, where it helps increase a pesticide’s ability to dissolve in water. TEA is used as a surfactant in agrochemicals to help pesticides disperse into crops.

MEA acts as a plasticizing agent, and chemical manufacturing plants may use MEA to remove carbon dioxide from ammonia gas in the production of synthetic ammonia.

The Cosmetic Ingredient Review has found that ethanolamine ingredients are safe as currently used in cosmetics and personal care products. FDA includes TEA, DEA and ethanolamine on its list of allowed indirect food additives.

To protect workers in industrial settings, OSHA has established a permissible exposure limit (PEL) for ethanolamine at 3 ppm in the air and requires employers to control workplace exposure below that PEL.

What is Monoethanolamine (CAS: 141-43-5)?

Monoethanolamine, also known as ethanolamine or 2-amioethanol is both a primary amine and a primary alcohol.

Like other amines, monoethanolamine behaves as a weak base. It is a toxic, flammable, corrosive, colourless and viscous liquid and has the same odour as ammonia.

Monoethanolamine is produced by reacting ethylene oxide with aqueous ammonia. Diethanolamine and triethanolmine are also produced from this reaction.

Monoethanolamine

Monoethanolamine (MEOA) belongs to the class of ethanolamines, with both primary amine and hydroxyl functionality.

Coatings

Monoethanolamine (MEOA) is used as a building block, ph-control agent as well as a dilution agent.
Inks

MEOA is used as a pH control agent in the formulation of packaging and printing inks
Other

Ethanolamines combine the properties of amines and alcohols in one molecule. They exhibit the unique capability of undergoing reactions common to both groups (bifunctioncal). As amines, they are mildly alkaline and react with acids to form salts or soaps. As alcohols they can can be transformed to ethers and esters. Ethanolamines are miscible with water, most alcohols and polyols.
Most of their industrial applications are dependent to some degree on these features.

Applications include the production of wood-treatment chemicals, detergents and surfactants.

Products are offered pure and in solutions with water.

Monoethanolamine is an organic compound that is the simplest type of amine. It is a colorless liquid with a mild, neutral odor. Monoethanolamine has been shown to be an effective antimicrobial agent, inhibiting bacterial growth by reacting with water vapor and nitrogen atoms in the environment. Monoethanolamine has also been shown to inhibit the production of nitric oxide and other reactive nitrogen species, which may account for its antimicrobial properties. The inhibition of nitric oxide synthesis may also account for monoethanolamine’s ability to improve locomotor activity in mice. This chemical can be used as a reagent in analytical methods such as gas chromatography and solid phase microextraction.

Melamine

admin — Tue, 24 Jan 2023 18:41:15 +0000

Melamine forms synthetic resins with formaldehyde. It remains largely non-metabolized in male Wistar rats with 90% of the administered dose excreted in the urine and thus acts as a non-protein nitrogen food additive found in milk. Drinking water contaminant candidate list 3 (CCL 3) compound as per United States Environmental Protection Agency (EPA), environmental, and food contaminants. Melamine is an organic-based, nitrogen-rich compound used to manufacture cooking utensils, plates, plastic products, and more. Melamine resin is durable, fire and heat resistant and virtually unbreakable, making melamine products more desirable than other plastic housewares.

Melamine is a nitrogen-containing heterocyclic amine that is used as a flame retardant, plasticizer, and textile dye. The toxicity of melamine has been evaluated in animal studies, which showed that it has low acute oral toxicity but high inhalation and dermal toxicity profiles. The acute effects of melamine are due to its capacity to bind to the erythrocyte membrane and cause hemolysis. Melamine can also react with cyanuric acid to form cyanuramide, which can be detected by gas chromatography/mass spectrometry (GC/MS) analysis. The carcinogenic potential of melamine has not been determined, but there is evidence that it may be genotoxic and have the potential to induce cancer in humans.

Manufacture and applications of melamine
Melamine can be manufactured from dicyandiamide, hydrogen cyanide, or urea. Modern commercial production of melamine typically employs urea as a starting material. Urea is broken down to cyanuric acid, which then can be reacted to form melamine. Its most important reaction is that with formaldehyde, forming melamine-formaldehyde resins of high molecular weight. These compounds form under the influence of heat and then become fixed into an insoluble and infusible mold; this process is known as thermosetting. Melamine-based thermoset materials contain cross-linked polymers, which make the fixed molds strong and durable. Usually formulated with fillers and pigments, melamine resins can be molded into dishes, containers, utensils, handles, and the like or used as laminating agents or coating materials for wood, paper, and textiles. Formica and Melmac are well-known trade names for products based on melamine resins.

Melamine has also been incorporated into a variety of flame-retardant materials. This application is based on the compound’s high nitrogen content. When exposed to heat, melamine degrades and releases nitrogen. The freed nitrogen takes the place of oxygen in the surface air surrounding the material, which prevents the material from burning. Butylated melamine resins, made by incorporating butyl alcohol into the melamine–formaldehyde reaction mixture, are fluids used as ingredients of paints and varnishes. A copolymer containing melamine, formaldehyde, and sodium bisulfite produces a foam with sound-absorbing and flame-retardant properties. The foam has a notably hard microbubble structure, which gives it an abrasive quality that has been utilized in the development of cleaning products.

Melamine is the organic compound with the formula C3H6N6. This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton. It is widely used in production of certain plastics, e.g. Formica. Like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred.

DESCRIPTION
In one large scale application, melamine is combined with formaldehyde and other agents to produce melamine resins. Such resins are characteristically durable thermosetting plastic used in high pressure decorative laminates such as Formica, melamine dinnerware, laminate flooring, and dry erase boards.

Melamine foam is used as insulation, soundproofing material and in polymeric cleaning products, such as Magic Eraser.

Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.

Melamine also enters the fabrication of melamine poly-sulfonate used as superplasticizer for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during its handling and pouring. It results in concrete with a lower porosity and a higher mechanical strength, exhibiting an improved resistance to aggressive environments and a longer lifetime.

IUPAC Name

tert-butyl methyl ether

HIGH PURITY- METHYL TERTIARY BUTYL ETHER (HP-MTBE), CAS 1634-04-4

Methyl Tertiary Butyl Ether (MTBE)

Formed by the blending of chemicals like methanol and isobutylene, Methyl tert-butyl ether (MTBE) is a colorless liquid and has a distinctive odour. The vapors of this chemical are denser than both narcotic and air. The boiling point of MTBE is 131-degree F with the flashpoint being 18-degree F. MTBE is miscible in water as it is less dense than water. This is why this chemical can be used as an octane booster for gasoline.

Methyl tert-butyl ether (MTBE) has been used since the 1980s as an additive to achieve a more efficient burning, especially for unleaded petrol. It can also be used for medical reasons to dissolve the gall bladder stone. MTBE is directly delivered to the patient’s gall bladder with the help of tubes. The tubes are surgically inserted into the patient for safety reasons.

Methyl and tert butyl are the two-alkyl components in methyl butyl ether. This solution is a metabolite, a fuel additive and a non-polar solvent. When combined with gasoline, MTBE is known to increase the oxygen and octane levels and reduce pollution, which is remarkable.

Methyl tert-butyl ether (MTBE) has several medical applications as well and is used as a solvent for synthesizing APIs.

Description

Methyl-tert-butyl ether, also known as tert-butyl methyl ether, methyl t-butyl ether or MTBE, is classified as a member of the dialkyl ethers. Dialkyl ethers are organic compounds containing the dialkyl ether functional group, with the formula ROR’, where R and R’ are alkyl groups. Methyl-tert-butyl ether is considered to be soluble (in water) and basic. It is used as a gasoline additive. Exposure may occur by breathing air contaminated with auto exhaust or gasoline fumes while refueling autos. Respiratory irritation, dizziness, and disorientation have been reported by some motorists and occupationally exposed workers. Acute (short-term) exposure of humans to methyl tert-butyl ether also has occurred during its use as a medical treatment to dissolve cholesterol gallstones. Chronic (long-term) inhalation exposure to methyl-tert-butyl ether has resulted in central nervous system (CNS) effects, respiratory irritation, liver and kidney effects, and decreased body weight gain in animals. United States Environmental Protection Agency has not classified methyl-tert-butyl ether with respect to potential carcinogenicity. (ChemoSummarizer)

Incompatible with oxidizing agents and strong bases. Avoid conditions like flames and sparks.

DESCRIPTION
Unlike the other common ketone solvents, acetone and MEK, MIBK has quite low solubility in water, making it useful for liquid-liquid extraction. It is commonly used as a solvent in paints, lacquers, varnishes and adhesives. MIBK is also used as a chemical intermediate in the synthesis of a rubber anti-ozonant additive in tyres. It has a similar polarity to ethyl acetate, but greater stability towards aqueous acid and base. It can be used to extract gold, silver and other precious metals from cyanide solutions, such as those found at gold mines, to determine the levels of those dissolved metals. Diisobutyl ketone (DIBK), a related lipophilic ketone, is also used for this purpose. Methyl isobutyl ketone is also used as a denaturing agent for denatured alcohol. When mixed with water or isopropyl alcohol MIBK serves as a developer for PMMA electron beam lithography resist. MIBK is used as a solvent for CS in the preparation of the CS spray used currently by British police forces.

Methyl Isobutyl Ketone (MIBK) by Junyuan Petroleum Group is used as a solvent for adhesive systems. It exhibits a faint ketonic and camphor-like odor. This solvent is stable and does not polymerize. Methyl Isobutyl Ketone (MIBK) is highly compatible with a variety of organic reagents. The shelf life of this product is 1 year.
