(4R-cis)-4,4a,5,6,7,8-hexahydro-4,4a-dimethyl-6-(1-methylethylidene)naphthalen-2(3H)-one Chemical Properties,Uses,Production
Description
α-Vetivone has a powerful, warm, pleasant, Orris-Vetiver-Ambre-like odor of outstanding tenacity. It is generally considered the most desirable odor of the two. Unfortunately, it appears to be the minor component of the total ketones in Vetiver oil.
Uses
α-Vetivone, is a component of Vetiver essential oil which is a highly esteemed basic ingredient of modern perfumery, hvaing a woody, earthy scent.
Definition
ChEBI: Alpha-Vetivone is a sesquiterpenoid.
