Allyl methyl sulfide
# Allyl methyl sulfide

Allyl methyl sulfide is an organosulfur compound with the chemical formula $CH_2=CHCH_2SCH_3.$ The molecule features two functional groups, an allyl $(CH_2=CHCH_2)$ and a sulfide. It is a colourless liquid with a strong odor characteristic of alkyl sulfides. It is a metabolite of garlic, and "garlic breath" is attributed to its presence.

It is prepared by the reaction of allyl chloride with sodium hydroxide and methanethiol.

    $CH_2=CHCH_2Cl$ + NaOH (aq) + $CH_3SH$ → $CH_2=CHCH_2SCH_3$ + NaCl + $H_2O$
