Cycloheptadeca-9-en-1-one has an obnoxious animal-gland odor. It can be pleasant at extreme dilutions.
CIVETONE is a colorless
liquid with warm, sensual, animalic musky odor and extreme tenacity. It is
themain odoriferous constituent of civet.Civetonewas formerly prepared bymultistep
syntheses, for example. Recently, newer processes using dimethyl
(Z)-9-octadecendioate as starting material have been described. This is cyclized
by a Dieckmann condensation either in liquid or in gaseous phase.
(Z)-9-Octadecendioic acid is available by microbial oxidation of oleic acid with
Candida tropicalis.
It is used in fine fragrance compositions for, for example, toiletries and body
care products.
ChEBI: A macrocycle that is cycloheptadecanone with an unsaturation at position 9 (the 9Z-stereoisomer). It has been found in African Civets.
From aleuritic acid, the trans- form only; the cis- and trans-forms from ethyl-9-keto heptadecanedioate.
A skin irritant. When
heated to decomposition it emits acrid
smoke and irritating fumes.
