Cyclohexanone is a toxic, flammable, cyclic, six-carbon organic molecule with a ketone functional group. Applications for the compound include use in the production of nylon, as a chemical reaction medium, and as a solvent. Cyclohexanone is used as a solvent for photoresist, an edge bead remover, and a general solvent for organic polymers resists.

Cyclohexanone (also known as ketohexamethylene, pimelic ketone, sextone, cyclohexyl ketone, nadone, anone, anon, cyclohexanon or hexanon), is an organic compound with the formula C6H10O and CAS No. 108-94-1. Structurally, it is a cyclic, six-carbon ketone derived from cyclohexane, with the addition of a single oxo functional group. It is a clear, colorless-to-pale-yellow, oily liquid that has limited miscibility with water. However, it is highly miscible with a range of other organic solvents such as acetone, ether, or alcohol. It has a slightly peppermint, acetone-like odor. Physical data: boiling point 155°C; density 0.947g/cm³; melting point −47.0°C.

Cyclohexanone Uses in Industrial Chemistry
• As a stock chemical for the manufacture of nylon (via conversion to adipic acid)
• As an intermediate in the synthesis of industrial products, especially pharmaceuticals, herbicides, insecticides, dyes, rubbers, and plasticizers
• As an industrial solvent for resins, waxes, fats, and cellulose lacquers
• As a metal degreasing solvent or cleaner
• As a precursor for organic synthesis, and sometimes as a solvent, in the research laboratory

This product is available in a range of purity grades depending on the application, for example, ‘extra pure’ or ‘suitable for analysis’.

Cyclohexanone is a corrosive, highly flammable liquid, and is harmful if inhaled. Storage in a cool, secure location is therefore recommended. When using this product, the information and advice given in the Safety Data Sheet should be observed. Due attention should also be given to the appropriate precautions necessary for handling chemicals.
