Chemical Information
FooDB Name4-Mercapto-4-methyl-2-pentanone
Description4-Mercapto-4-methyl-2-pentanone, also known as 4-sulfanyl-4-methylpentan-2-one or 4-methyl-4-sulfanyl-2-pentanone, 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. Thus, 4-mercapto-4-methyl-2-pentanone is considered to be an oxygenated hydrocarbon. 4-Mercapto-4-methyl-2-pentanone is a blackcurrant, box tree, and cat-urine tasting compound. 4-Mercapto-4-methyl-2-pentanone has been detected, but not quantified in, alcoholic beverages and grape wine. This could make 4-mercapto-4-methyl-2-pentanone a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 4-Mercapto-4-methyl-2-pentanone.
