Chemical Information

FooDB Name

Methylisopropyl ketone

Description

Methylisopropyl ketone, also known as isopropyl methyl ketone or 2-acetylpropane, is a member of the class of compounds known as ketones. Ketones 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, methylisopropyl ketone is considered to be an oxygenated hydrocarbon lipid molecule. Methylisopropyl ketone is soluble (in water) and an extremely weak acidic compound (based on its pKa). Methylisopropyl ketone is a camphor tasting compound found in guava and potato, which makes methylisopropyl ketone a potential biomarker for the consumption of these food products.
