Uses
Uses in perfumery :
Dimethyl Sulfide is used in small quantities in exotic and red fruits, woody, green and eau fraiche notes. In low quantity, it brings a juicy and acidic effect to fruity notes, but an onion facet if overdosed.
Year of discovery :
Data not available.
Natural availability :
Dimethyl Sulfide is present in many foods consumed daily, but its synthetic version in most often used in perfumery.
Isomerism :
Dimethyl Sulfide does not have any isomer used in perfumery.
Synthesis precursor :
Dimethyl Sulfide is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
The synthesis of Dimethyl Sulfide consists of a single step: reacting two molar equivalents of bromomethane with one and a half equivalent of sodium sulfide, in a hydroalcoholic and hot medium.
