Benzylacetone Usage And Synthesis

Chemical Properties

Clear colorless to pale yellowish liquid

Chemical Properties

has been identified as a volatile component of cocoa. Benzylacetone is a sweet-floral-smelling liquid, which can be prepared by selective hydrogenation of benzylidene acetone (from benzaldehyde and acetone). It is used in soap perfumes.

Uses

4-Phenyl-2-butanone be used as an attractant for melon flies and as an odorant for soap. It is also used in the preparation of 4-oxocyclohexanecarbaldehyde derivatives.

Uses

4-Phenyl-2-butanone may be used as an analytical standard for the determination of the analyte in volatile oils, as well as agarwood extracts of Aquilaria malaccensis, yeast cell culture, and biological samples by various chromatography based techniques.

Uses

4-Phenyl-2-butanone is an attractant compound found in the flower Nicotiana attenuata. It is also used in the preparation of 4-oxocyclohexanecarbaldehyde derivatives.
