Metabolite Identification
Common Name2-(Methylthio)ethanol
Description2-(Methylthio)ethanol, also known as 2-methylmercaptoethanol or 2-(methylsulfanyl)ethanol, belongs to the class of organic compounds known as dialkylthioethers. These are organosulfur compounds containing a thioether group that is substituted by two alkyl groups. 2-(Methylthio)ethanol is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-(Methylthio)ethanol is a meaty and sulfurous tasting compound. Outside of the human body, 2-(Methylthio)ethanol has been detected, but not quantified in, mung beans and soy beans. This could make 2-(methylthio)ethanol a potential biomarker for the consumption of these foods. A primary alcohol that is the S-methyl derivative of mercaptoethanol.
