Common Name3-mercapto-4-methyl-2-pentanone
Description4-methyl-3-sulfanylpentan-2-one 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. Based on a literature review very few articles have been published on 4-methyl-3-sulfanylpentan-2-one.
