Tert-butyl mercaptan is a foul-smelling organosulfur compound which is a colorless, clear liquid at ambient temperatures. It is primarily used as an odorant for natural gas, and it has an odor threshold of less than 0.33 ppb. Non-toxic at the very low concentrations used in natural gas, but the smell can cause nausea at concentrations as low as 2-3 ppm.
