Metabolite Identification
Common Name2-Methylbenzenethiol
Description2-Methylbenzenethiol belongs to the class of organic compounds known as thiophenols. Thiophenols are compounds containing a thiophenol ring, which a phenol derivative obtained by replacing the oxygen atom from the hydroxyl group (attached to the benzene) by a sulfur atom. 2-Methylbenzenethiol is an egg, garlic, and meaty tasting compound. Based on a literature review very few articles have been published on 2-Methylbenzenethiol.
