Chemical Information
FooDB NameS-Methyl propanethioate
DescriptionS-Methyl propanethioate, also known as S-methyl thiopropanoate, belongs to the class of organic compounds known as thioesters. These are organic compounds containing an ester of thiocarboxylic acid, with the general structure RC(=S)XR' (R=H, alkyl, aryl; R'=alkyl, aryl; X=O,S). S-Methyl propanethioate is an extremely weak basic (essentially neutral) compound (based on its pKa). S-Methyl propanethioate is an alliaceous, dairy, and milky tasting compound.
