Metabolite Identification
Common Name3-Mercapto-2-butanone
Description3-Mercapto-2-butanone belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. 3-Mercapto-2-butanone is a gassy, meaty, and onion tasting compound. Based on a literature review a significant number of articles have been published on 3-Mercapto-2-butanone.
