S-Methyl butanethioate(CAS: 2432-51-1)

S-Methyl butanethioate (CAS: 2432-51-1) is a colorless or pale yellow liquid with a fruity odor. Its molecular weight is 118.17 g/mol. It has a high solubility in organic solvents but is only slightly soluble in water. It is thermally unstable and can undergo hydrolysis. It reacts with strong acids and bases to form corresponding products.

S-Methyl butanethioate can be synthesized by the addition of methional to methyl iodide in the presence of a base like sodium hydroxide. The reaction is performed in an organic solvent at room temperature. This method provides good yields and good selectivity.

S-Methyl butanethioate is widely used in the agricultural sector as a pesticide, in the food industry as a flavoring agent, and in the pharmaceutical industry for the synthesis of certain sulfur-containing compounds. It is also used in some polymer formulations and as a reagent in analytical chemistry.

S-Methyl butanethioate is a flammable liquid and should be handled in a well-ventilated area. It should be stored in tightly closed containers in a cool, dry place away from incompatible materials. Eye protection, gloves, and appropriate protective clothing should be worn during handling. In case of spill, it should be handled according to the Material Safety Data Sheet (MSDS/SDS) guidelines.
