14methylphenylethanone

14methylphenylethanone, also known as 4-methylacetophenone, is an organic compound with the chemical formula C9H10O. It is a ketone and a derivative of acetophenone, with a methyl group attached to the phenyl ring at the para position.

This compound is a colorless to pale yellow liquid with a characteristic sweet, floral, and slightly fruity odor, often described as resembling hawthorn or mimosa. Its scent makes it a valuable ingredient in perfumery and flavorings, where it is used to impart floral and fruity notes. It can be found naturally in some essential oils, such as ylang-ylang.

Industrially, 4-methylacetophenone is synthesized through various chemical processes, commonly involving the Friedel-Crafts acylation of toluene with acetyl chloride or acetic anhydride. It serves as an intermediate in the synthesis of other chemicals, including pharmaceuticals and agrochemicals. Its properties also lend themselves to applications in research laboratories.

In terms of safety, 4-methylacetophenone is generally considered to have low toxicity, but it can be an irritant to the skin and eyes. Standard laboratory precautions, such as wearing gloves and eye protection, are recommended when handling this substance. Its flammability is moderate.
