Appearance

Colorless liquid.

Odor

Powerful green foliage odor, less pungent and less sharp than the Methyl heptin carbonate, and not as fatty, overall more oily, yet pleasant.

Uses in perfumery

Finds some use in perfumery, although always in extremely low concentration, as a modifier for lower alkyl heptin or alkyl octin carbonates, not only for Violet fragrances, but also for other florals, such as Narcisse, Tuberose, Gardenia, etc.

Production

Produced from Octyne via Octyne sodium with iso-Amyl chloroformate to form the ester.
