3-PHENYLPROPYL ISOBUTYRATE

CLEAR COLOURLESS LIQUID

3-Phenylpropyl isobutyrate has a sweet, balsamic odor and a bittersweet flavor reminiscent of peach. It has a finer and fresher odor than the corresponding n-butyrate.

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.

By esterification of hydrocinnamic alcohol with n-butyric acid.

3-Phenylpropyl isobutyrate belongs to the cinnamyl phenylpropyl group of fragrance materials. It is the key volatile constituent of Roman camomile essential oil.
