BENZYL ISOVALERATE Usage And Synthesis

Chemical Properties

BENZYL ISOVALERATE is a liquid with a heavy, floral odor, which is used in perfumery for oriental and heavy blossom odors.

Chemical Properties

Benzyl isovalerate has a powerful, fruity apple odor.

Occurrence

Reported found in cherimoya (Anonna cherimoli Mill.), sapodilla fruit and lambs’ lettuce (Valerianella locusta).

Uses

Sometimes used in perfume formulations for Oriental fragrance types - it blends well with Opopanax - in Rose bases, Fougercs, and in novelty-type fragrances (Tobaccoeffect, etc.). It is somewhat fresher-floral than the n-valerate. Used in flavour compositions for imitation Apple, Apricot, Banana, Cherry, Cheese, Pineapple, Raspberry, Walnut, etc. It is also suggested for use in Tobacco flavours. Concentrations are usually about 50 ppm in the finished product but may be as high as 200 ppm in chewing gum.

Preparation

May be prepared by esterification of isovaleric acid with benzyl alcohol.

Definition

ChEBI: Benzyl 3-methylbutanoate is a carboxylic ester. It is functionally related to a benzyl alcohol.

Taste threshold values

Taste characteristics at 20 ppm: sweet, fruity and balsamic with tropical and dried fruit nuances.
