Faint, sweet-aromatic odor, rather nondescript.

Uses in perfumery

The alkyl-substituted derivatives of this lactone are extremely interesting, and many of them have been used extensively for several decades in perfumes and flavors.

Uses in flavor

Has been suggested for use in flavor compositions, but it is most conceivable that its lack of power has prevented this lactone from becoming a standard item on the flavorist’s shelf.

Production

Produced from: 1) Vinylacetic acid. 2) Glutaric acid. 3) Propion chlorohydrin via the Cyanhydrin.
