Metabolite Identification
Common Name2-Methyl-3-hexanone
Description2-Methyl-3-hexanone 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. 2-Methyl-3-hexanone is an extremely weak basic (essentially neutral) compound (based on its pKa).
