      an organic compound used as an ingredient in perfumes (perfume) and as a chemical intermediate in the manufacture of pharmaceuticals (pharmaceutical), resins (resin), flavouring agents, and a form of tear gas. It also has been used as a drug to induce sleep.

      The compound can be synthesized from benzene and acetyl chloride, but it is prepared commercially by the air oxidation of ethylbenzene.

      Pure acetophenone is a colourless liquid, with a melting point of 20.2 °C (68.4 °F) and a boiling point of 202.4 °C (396.3 °F). It is only slightly soluble in water but is freely soluble in ethanol ( ethyl alcohol), diethyl ether (ethyl ether), and chloroform.
