Dry-fruity, unripe-Apricot-type odor with Ambrc-like background. The flavor in dilutions below 5 ppm is fairly pleasant, but has a somewhat confusing picture of Ambrc-like or perfumey notes with Apricot-peach admixture.

Physical properties

Colorless or very pale straw-colorcd oily liquid. B.P. 251°C. Sp.Gr. 0.95.
Insoluble in water, soluble in alcohol and oils. Poorly soluble in Propylene glycol.

Production Methods

Alpha-hexyl-gamma-butyrolactone can be produced from n-Hexyl malonic ester and Ethylene oxide.
