TERTIARY BUTYL MERCAPTAN Chemical compatibility with O-rings, rubbers, & plastics

Tert-Butyl mercaptan (TBM) is a colorless to pale yellow liquid with a strong, unpleasant odor, having the chemical formula C4H10S. It is used primarily as an odorant for natural gas and liquefied petroleum gas (LPG), providing a detectable warning in case of leaks. Tert-butyl mercaptan is also employed as an intermediate in the synthesis of certain chemicals and pharmaceuticals. Proper handling and storage of TBM are essential to prevent accidents and ensure safety, as it is flammable and can pose health risks if inhaled or ingested. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with TBM. Its effectiveness as an odorant and its unique properties make tert-butyl mercaptan a valuable chemical in the natural gas industry and other applications requiring leak detection and safety measures.
