Appearance

Colorless slightly oily liquid.

Solubility

Insoluble in water, almost insoluble in propylene glycol, glycerin and mineral oil, soluble in alcohol and perfume or flavor materials.

Odor

Powerful and very diffusive leafy-rosy-musk odor with exceptional topnote effect. Distinctly fresher and more diffusive than the n-Butylester. Slightly waxy notes are typical of the pure product, while unpleasant or pronounced animal-honeylike notes dominate the poorer grades.

Flavor

Useful in flavor compositions for imitation butter, caramel, chocolate, tutti-frutti, honey, nut, and in mere traces as a lift in mint flavors for mouthwash.

Uses in perfumery

Finds extensive use in perfumery for fresh petal notes in rose, peony, narcisse, carnation, sweet pea, freesia, hyacinth, etc.

Production

Produced by direct esterification of iso-Butanol with phenylacetic acid under azeotropic conditions, or directly from benzyl cyanide and iso-Butanol under acid conditions.
