Other names :
Grapefruit Mercaptan ; Menthenethiol ; 2-(4-methyl-1-cyclohex-3-enyl)propane-2-thiol ; Para-menth-1-ene-8-thiol ; 1-para-menthen-8-thiol ; Para-menthene thiol ; Terpinyl mercaptan ; Alpha,alpha,4-trimethyl cyclohex-3-ene-1-methane thiol
Volatility :
Head
Uses in perfumery :
Grapefruit Mercaptan is used in sulfuric, fruity-exotic and vegetable notes. Also used in colognes and eaux fraiches as a booster. Often diluted directly in D-Limonene by suppliers.
Natural availability :
Natural Grapefruit Mercaptan can be extracted from Grapefruit EO. However, synthetic Grapefruit Mercaptan is most often used in perfumery.
Year of discovery :
Data not available.
Other comments :
When it is pure, only a very powerful sulfured smell is detected. In dilution, the smell of Grapefruit Mercaptan becomes more pleasant and reminisces of grapefruit

Synthesis route :
Grapefruit Mercaptan is synthesized in an alkaline medium, by reaction between hydrogen sulfide and the corresponding alcene, derived from para-Menthene.
Synthesis precursor :
Grapefruit Mercaptan is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Grapefruit Mercaptan has an asymmetric carbon. However, the distinction between the two possible enantiomers is not made in perfumery. It is the mixture of the two isomers that is used in majority. The isomer (R) of the molecule is considered more powerful, as it has an extremely low detection limit of 200 nanograms/kg, against 800 for the isomer (S).
