Chemistry & Uses
Uses in perfumery :
Dimethyl Octenone is used in grapefruit notes and in fruity notes to bring a minthy nuance and depth. Also used in buchu or mint notes to bring a slightly zesty note.
Year of discovery :
Data not available.
Natural availability :
Dimethyl Octenone is not found in nature.
Isomerism :
Dimethyl Octenone has an asymmetric carbon, giving rise to two possible enantiomers for this molecule. Nevertheless, the ingredient used in perfumery is a mix of the enantiomers of the molecule. Dimethyl Octenone is also a constitutional isomer of Linalool and Geraniol, among others, meanwhile it doesn't have the same smell as its isomers used in perfumery.
Synthesis precursor :
Dimethyl Octenone is not used for the synthesis of another molecule used in perfumery.
Synthesis route :
Dimethyl Octenone can be synthesized by an alkylation reaction engaging diethyl ketone and prenyl chloride.
Stability :
Unstable in very acidic and very alkaline products.
Other comments :
Dimethyl Octenone is part of the terpenes family. These are molecules frequently synthesized by a Diels-Alder reaction, making the number of carbons in the empirical formula a multiple of five.
