The Uses of 3-PHENYLPROPYL ISOBUTYRATE

3-Phenylpropyl isobutyrate finds some use in Jasmin compositions, partly as a modifier for Benzyl-isobutyrate, partly as a supporting note for fruity-balsarnic ingredients. It works well with Styrax, which tends to produce a rather "dead" note in floral compositions.
3-Phenylpropyl isobutyrate also finds use in flavor compositions, mainly in imitation Apple, Apricot, Peach, Pear, Pineapple, Plum, Quince, etc. and the concentration used is equivalent to about 1 to 5 ppm in the finished product.

Preparation

By esterification of hydrocinnamic alcohol with n-butyric acid.
