ETHYL MERCAPTAN Chemical compatibility with O-rings, rubbers, & plastics

Ethyl mercaptan, also known as ethanethiol, is a colorless liquid with a strong odor, represented by the chemical formula C2H6S. It is used as a warning agent in propane and natural gas, and as an intermediate in the synthesis of various chemicals. Ethyl mercaptan is highly flammable and can cause skin and respiratory irritation. Proper handling, storage, and the use of personal protective equipment (PPE) are essential to ensure safety.
