Uses
Propyl benzoate has a nutty odor and sweet fruity or nut-like taste, and as such, it is used as a synthetic flavoring agent in foods. It also has antimicrobial properties and is used as a preservative in cosmetics. It occurs naturally in the sweet cherry and in clove stems, as well as in butter.[1][3]
Reactions
Propyl benzoate can be synthesized by the transesterification of methyl benzoate with propanol.[3] Propyl benzoate can also be synthesized by means of Fischer esterification of benzoic acid with propanol.
