Identification
Common Name5-Methyl-2-hexanone
ClassSmall Molecule
Description5-Methyl-2-hexanone is found in animal foods. 5-Methyl-2-hexanone is a volatile component in fruit pulp of papaya (Carica papaya), black tea aroma and in cooked beef and egg aroma 5-Methyl-2-hexanone belongs to the family of Ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be H) [1]. (Reference: [1] IUPAC. Compendium of Chemical Terminology, 2nd ed.

Chemical Taxonomy
Description 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.
