Benzylacetone (IUPAC name: 4-phenylbutan-2-one) is a liquid with a sweet, flowery smell that is considered to be the most abundant attractant compound in flowers (e.g. Coyote Tobacco, Nicotiana attenuata)[1][2] and one of volatile components of cocoa.

[3] It can be used as an attractant for melon flies (Bactrocera cucurbitae),[4][5] in perfume,[6] and as an odorant for soap.

It can be prepared by the hydrogenation of benzylideneacetone.
