Ethyl mercaptan is a liquid that has a strong, unpleasant odor. It is used as an odorant in natural gas and as a chemical intermediate. Ethyl mercaptan is synthesized from ethanethiol and an isothiouronium salt by the transfer of a methyl group. The reaction mechanism of ethyl mercaptan involves hydrophobic effect, steric interactions, and intermolecular hydrogen bonding.

Ethanethiol acts as a stabilizer for adhesives and an odorant for natural gas. It is used in the odorless liquefied petroleum gas (LPG) in order to find out the gas leaks. It is used as key starting material for the preparation of ethylsulfonic acid, diethyldisulfide and sodium ethylmercaptide. Further, it is also used in the underground mining industry as stench gas. In organic synthesis, it gives powerful nucleophile set- in the presence of sodium hydroxide. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
