Appearance

Colorless oily liquid

Solubility

Practically insoluble in water, soluble in alcohol and oils

Odor

Warm-herbaceous, slightly winey-sweet, moderately tenacious odor

Uses in perfumery

This rare ester has been suggested for use in certain artificial essential oils, and as a novel note in warm-herbaceous bases, in support of Chamomile, Clary Sage, Lavender, etc. for Chypre and modern herbaceous-fruity fragrance types.

Uses in flavor

Although there is no apparent indication that the material is used in flavor compositions, the author finds it quite possible that it could eventually be used as a bouquetting material in Butterscotch, Caramel, Rum, fruit complexes, Plum, etc.

Production

Produced from asymmetric-Dimethyl succinyl chloride plus Zinc ethyl, followed by esterification of the resulting acid with n-Propanol. Other methods are known.
