2,6-Dimethyl-7-octen-2-ol Usage And Synthesis
- Chemical PropertiesDihydromyrcenol is a colorless liquid with a fresh citrus-like odor and a lavender note. It is obtained from 3,7-dimethyl-1,6- octadiene (citronellene), the pyrolysis product of cis-pinane and can be prepared by three different processes: (i) by addition of hydrogen chloride and subsequent hydrolysis of the resulting 2,6-dimethyl-2-chloro-7-octene; or (ii) by addition of formic acid and subsequent saponification of the resulting dihydromycrenyl formate; or (iii) by direct hydroxylation with 60–80% sulfuric acid.Dihydromyrcenol is used in fine fragrances as well as in soap and detergent perfumes for fresh lime and citrus-like floral notes.
- OccurrenceFound in the leaf oils of Barosma venusta and in the oil of hops (Gildemeister & Hoffman, 1960)
- PreparationPrepared by adding hydrogen chloride to myrcene followed by hydrolysis under mild conditions (Bedoukian, 1967)
- DefinitionChEBI: A monoterpenoid that is oct-7-en-2-ol substituted by methyl groups at positions 2 and 6 respectively.
