Ethyl Mercaptan is a colorless, flammable gas with a strong odor, often described as resembling rotten eggs. It is primarily used as an odorant for natural gas, which is otherwise odorless, to help detect leaks. This compound is also known as ethanethiol and has the chemical formula C2H6S. In addition to its use in natural gas, Ethyl Mercaptan is utilized in the production of various chemicals and as a flavoring agent in food. Due to its potent smell, even small amounts can be easily detected, making it an effective safety measure in industries that handle gases.
