Ethanethiol, or ethyl mercaptan, is best known as the smell of a natural gas leak. It has been added to natural gas supplied to many areas because it can be identified by humans at the extremely low concentration of ~8.7 ppt. It is also used to treat petroleum processing catalysts, and as a precursor for herbicides and pesticides.
