S-Methyl thioacetate is a natural product found in many plant species. In its pure form it has an unpleasant sulfurous smell, but when highly diluted and along with other simple alkyl thioacetates and related compounds, it is an important component of the smell and flavour profile of some foods, especially Camembert cheese.[1][2]

Alternate isomer[edit]

O-methyl ethanethioate, CAS# 21119-13-1[3]

The constitutional isomer in which the oxygen and sulfur atoms are interchanged, O-methyl thioacetate, is also commonly known as methyl thioacetate and found as a natural product and flavor component in some foods, such as fish sauce and some kinds of melon.[4][5]
