METHYL MERCAPTAN 74-93-1

Methyl Mercaptan (CAS 74-93-1, CH4S), is a colorless gas, widely used in the production of pesticides, pharmaceuticals, and synthetic resins, with a strong and unpleasant odor resembling that of rotten cabbage. It is highly flammable and toxic, and can cause severe health effects if inhaled or ingested. Methyl mercaptan plays a crucial role as a precursor in the synthesis of various organic compounds, and is also used as an odorant in natural gas to detect leaks.
