DESCRIPTION

General description

In the solid-phase synthesis of oligonucleotides, liquid reagents are used in each step of the synthesis cycle. Overall synthesis performance, and therefore total product yield and purity of the crude oligonucleotide, is highly dependent on the chemical purity of the monomers and the supporting liquid reagents and other solvents like ethylacetate, dichloromethane, and dimethylformadine .Dichloromethane is an ordinary organic solvent frequently utilized in peptide synthesis. Under normal circumstances, DCM maintains highly stable and will not cause significant side reactions in peptide synthesis. It is a chlorinated organic solvent that is susceptible to degradation with time. This can be suppressed by adding amylene as a stabilizer.Dichloromethane has been tested as a solvent medium for the dipyridine-chromium(VI) oxide. Solubility was reported to be 12.5g/100ml. The role of the quantity of TiO2 loading on activated carbon support employed in the photodecomposition of dichloromethane has been investigated.

Application

Dichloromethane may be used as a solvent for the preparation of stock solutions of carotenoids. It may be employed as a solvent in the synthesis of polylactide-based (PLA) thin films. IT is also suitable as a solvent for the oxidation of primary and secondary alcohols using dipyridine-chromium(VI) oxide.
