Alkylthiols are organic compounds containing the thiol functional group linked to an alkyl chain. Ethanethiol is soluble (in water) and a very weakly acidic compound (based on its pKa). Ethanethiol is a fruity and sulfurous tasting compound found in potato, which makes ethanethiol a potential biomarker for the consumption of this food product. Ethanethiol may be a unique S.cerevisiae (yeast) metabolite. Ethanethiol, commonly known as ethyl mercaptan, is a clear liquid with a distinct odor. It is an organosulfur compound with the formula CH3CH2SH. Abbreviated EtSH, it consists of an ethyl group (Et), CH3CH2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with sulfur in place of oxygen. The odor of EtSH is infamous. Ethanethiol is more volatile than ethanol due to a diminished ability to engage in hydrogen bonding. Ethanethiol is toxic. It occurs naturally as a minor component of petroleum, and may be added to otherwise odorless gaseous products such as liquefied petroleum gas (LPG) to help warn of gas leaks. At these concentrations, ethanethiol is not harmful . 1-ethylthiol 1-Mercaptoethane 811-50-7 (mercury(+2) salt) Aethanethiol Aethanethiol (german) Aethylmercaptan Aethylmercaptan (german) C2H5SH Etantiolo Ethaanthiol Ethanethiol (ethyl mercaptan) Ethanethiol, sodium salt Ethyl hydrosulfide Ethyl mercaptan Ethyl mercaptan [UN2363] [Flammable liquid] Ethyl sulfhydrate Ethyl thioalcohol Ethyl-mercaptan Ethylmercaptaan Ethylmerkaptan Etilmercaptano LPG ethyl mercaptan 1010 Mercaptan C2 Mercaptoethane Methanethiol Quadrapure(TM) bis(ethyl mercaptan) Quadrapure(TM) det SCC Thioethanol Thioethyl alcohol Thioethyl group C2H6S 62.134 62.019020882 ethanethiol ethanethiol 75-08-1 CCS InChI=1S/C2H6S/c1-2-3/h3H,2H2,1H3 DNJIEGIFACGWOD-UHFFFAOYSA-N belongs to the class of organic compounds known as alkylthiols.
