S-Methyl ethanethioate(CAS: 1534-08-3)

S-Methyl ethanethioate (CAS: 1534-08-3) is a colorless to slightly yellow liquid with a slightly pungent odor. It has a molecular weight of approximately 116.15 g/mol and a boiling point of 92-93°C. This compound is slightly soluble in water but miscible with ethanol and other organic solvents. It is moderately reactive, particularly towards nucleophiles, and can undergo hydrolysis to form thiols and carboxylic acids.

S-Methyl ethanethioate can be synthesized by the reaction of ethanethiol with methyl iodide in the presence of a base such as potassium carbonate. The reaction is typically conducted in a solvent like acetonitrile at room temperature. High yields are achieved with good selectivity towards the desired product. This method is widely used due to its simplicity and good control over the reaction conditions.

S-Methyl ethanethioate (CAS: 1534-08-3) is used in various industries, including pharmaceuticals for the synthesis of certain drugs, polymers for modification and functionalization, and as a reagent in analytical chemistry for sensor applications. Its reactivity and ability to form stable products make it valuable in semiconductor processing for etching and deposition.

When handling S-Methyl ethanethioate (CAS: 1534-08-3), proper personal protective equipment (PPE) such as gloves and safety goggles should be worn. It should be used in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up immediately using appropriate absorbent materials. In case of contact, rinse the affected area with water. Always refer to the Safety Data Sheet (SDS) for detailed emergency procedures and storage guidelines.
