Isobutyl butyrate Chemical Properties,Uses,Production
Usee
Isobutyl butyrate is a metabolite of Rifampicin, a Rifamycin antibiotic.
Description
Isobutyl butyrate has a fruity odor reminiscent of apple or pineapple and a sweet flavor reminiscent of rum. May be prepared by esterification of butyric acid with isobutyl alcohol in the presence of concentrated H2S04; or by enzymatic action of hog pancreas on a mixture of isobutyl alcohol and butyric acid in the absence of water.
Chemical Properties
Isobutyl butyrate has a fruity, ethereal odor reminiscent of apple or pineapple and a sweet flavor reminiscent of rum.
Preparation
By esterification of butyric acid with isobutyl alcohol in the presence of concentrated H2SO4, or by enzymatic action of hog pancreas on a mixture of isobutyl alcohol and butyric acid in the absence of water.
Definition
ChEBI: A butyrate ester resulting from the formal condensation of butanoic acid with isobutanol. It is used as a food flavour ingredient for apple, banana, peach and pinapple flavours in ice cream and confectionery.
