Ethanethiol, 1-(methylthio)-, also known by its CAS number 31331-53-0, is an organosulfur compound characterized by the presence of both thiol and thioether functional groups. This compound features a two-carbon ethyl chain with a thiol (-SH) group at one end and a methylthio (-S-CH3) group at the other. It is typically a colorless to pale yellow liquid with a strong, unpleasant odor reminiscent of rotten cabbage or garlic, which is characteristic of many thiols. The compound is soluble in organic solvents and exhibits low solubility in water due to its hydrophobic methylthio group. Ethanethiol, 1-(methylthio)- is known for its reactivity, particularly in nucleophilic substitution reactions, and can participate in various chemical transformations involving thiol and thioether functionalities. It is used in organic synthesis and may also serve as an intermediate in the production of other sulfur-containing compounds. Due to its strong odor, it is often used as an odorant in natural gas to detect leaks.

1-(Methylthio)ethanethiol (MTET) is a highly volatile, naphthenic compound that has been shown experimentally to be a sulfide and ethanal precursor. It is also an ethyl cinnamate solvent. MTET is soluble in organic solvents such as chloroform and benzene. MTET has been used to produce polymers by coating sensor surfaces with polymer film and evaporating the solvent. The fluorescence of MTET increases in the presence of oxygen, which may be due to its oxidation by air.
