[Description]

Methyl 4-phenylbutyrate has a powerful, sweet, fruity, floral odor. Below 10 ppm, the flavor is extremely sweet and fruity. May be prepared by direct esterification of γγ-butyric acid.
[Chemical Properties]

Methyl 4-phenylbutyrate has a powerful, sweet, fruity, floral odor. The flavor becomes extremely sweet and fruity at concentrations below 10 ppm
[Uses]

Methyl 4-phenylbutanoate finds some use in flavor compositions, mainly as a modifier in Strawberry imitation, where is seems to do a better job, although perhaps not with the same power-as Methyl cinnamate and Methyl-hydrocinnamate. It is also used in trace amounts in Honey imitations and in various fruit complexes.
[Definition]

ChEBI: Methyl 4-phenylbutanoate is a fatty acid methyl ester.
[Preparation]

By direct esterification of γ-butyric acid.
