7-methoxy-3,7-dimethyloctan-2-ol

7-Methoxy-3,7-dimethyl-2-octanol is a clear, almost colorless liquid with sandalwood odor, which has a floral, woody note. It is not known to have been found in nature.
7-Methoxy-3,7-dimethyl-2-octanol is prepared by hydrochlorination of dihydromyrcene, methoxylation of the resulting 2-chloro-2,6-dimethyl-7-octene, and epoxidation. The alcohol is obtained by hydrogenation of the epoxide in the presence of Raney nickel and triethylamine. It is used in perfumery as a top note in high-quality sandalwood compositions for cosmetics, toiletries, and soaps.
