Ethanethiol is an alkanethiol that is ethane substituted by a thiol group at position 1. It is added to odorless gaseous products such as liquefied petroleum gas (LPG) to provide a garlic scent which helps warn of gas leaks. Ethyl mercaptan appears as a clear colorless low-boiling liquid (boiling point 97 °F) with an overpowering, garlic-like/skunk-like odor. Flash point -55 °F. Less dense than water and very slightly soluble in water.
