acetofenon

Acetophenone is an organic compound with the chemical formula C8H8O. It is also known by its common name, methyl phenyl ketone, or its IUPAC name, 1-phenylethanone. It is a colorless, viscous liquid that has a strong, sweet, floral odor, often described as resembling orange blossoms or hawthorn. This characteristic scent makes it a valuable ingredient in perfumery and flavoring applications.

Acetophenone is a ketone and is structurally characterized by a phenyl group attached to an acetyl group. It occurs naturally in some plants, such as bitter almond and lavender, and is also found in some foods and beverages. Industrially, it is primarily produced through the Friedel-Crafts acylation of benzene with acetyl chloride or acetic anhydride.

Beyond its use in fragrances and flavors, acetophenone serves as a precursor in the synthesis of various pharmaceuticals, including hypnotics and sedatives. It also finds application as a photoinitiator in UV-curing processes for inks and coatings, and as an intermediate in the production of other organic chemicals. Its relatively low toxicity and pleasant aroma contribute to its widespread use.
