5-ISOPROPYL-2-METHYL-CYCLOHEXANONE Usage And Synthesis

Description

May be prepared by oxidation of carvomenthol; from α-methyl- (β'-isopropyl pimelic acid, dimethyl ester.

Chemical Properties

p-Menthan-2-one has a spearmint odor and pungent taste.

Occurrence

Reported found in the oil of Blumea malcomii and Blumea eriantha; as a flavor component of cognac and in grapefruit peel oil, starfruit, corn mint oil and spearmint oil.

Preparation

By oxidation of carvomenthol; from α-methyl-β′-isopropyl pimelic acid, dimethyl ester. (+)-Carvomenthone is formed from (+)-dihydrocarvone in a divergent pathway.

Definition

ChEBI: Tetrahydrocarvone is a p-menthane monoterpenoid.

Aroma threshold values

Detection: 800 ppb to 1.12 ppm
