A bright, juicy fruity-green ester with a character reminiscent of unripe apple, pineapple and pear skin. Slightly waxy and rummy in the drydown, with a clean, natural fruit-peel freshness rather than candied sweetness.AI · claude-opus-4-7

Appearance

Colorless liquid.

Solubility

Almost insoluble in water, soluble in alcohol and propylene glycol, miscible with oils.

Odor

Powerful, but rather harsh-fruity, non-descript type of odor, even less natural than the n-Butyrate.

Uses in perfumery

The author believes that this ester is of very little interest to the perfumer or the flavorist.

Production

Produced by direct esterification of n-Hexanol with iso-Butyric acid under azeotropic conditions. Also from n-Hexanol and iso-Butyric anhydride.
