3,7-dimethyl-6-octen-1-yn-3-ol, also known as Dehydrolinalool, is a derivative of
methyl heptenone and acetylene. It
is used in small amounts for the production of chemical fragrances for daily use.
Industrial-grade dehydrolinalool (content 92–96%) is mainly used to synthesize a
series of perfumes such as linalool, nerolidol, citral and ionone, which are also important intermediates for the synthesis of vitamin A, E and K. Dehydrolinalool has a strong
ability to mask bad odors, especially for disgusting hydrogen sulfide, garlic preparations and polysulfide odors. In addition, it also has the role of mosquito repellent.
A sterol compound such as dehydrolinalool has excellent antibacterial activity against
Escherichia coli, Enterobacter faecalis, Proteus and the like. Dehydrolinalool has high
added value and is a fine chemical product with broad market prospects.
