Metabolite Identification

Common Name

2-Methyl-1-propanethiol

Description

2-Methyl-1-propanethiol belongs to the class of organic compounds known as alkylthiols. These are organic compounds containing the thiol functional group linked to an alkyl chain. 2-Methyl-1-propanethiol is a cooked, mustard, and vegetable tasting compound. 2-Methyl-1-propanethiol has been detected, but not quantified in, several different foods, such as alcoholic beverages, fruits, guavas (Psidium guajava), and milk and milk products. This could make 2-methyl-1-propanethiol a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 2-Methyl-1-propanethiol.
