S-Methyl thioacetate

S-Methyl thioacetate is the organosulfur compound with the formula. This colorless, malodorous liquid is 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 odor and flavour profile of some foods, including Camembert cheese, yogurt, and baijiu.

Alternate isomer

The constitutional isomer in which the oxygen and sulfur atoms are interchanged, O-methyl thioacetate, is also known as methyl thioacetate. It is not found in nature. It has mainly been the subject of theoretical studies.
