Chemical Information
FooDB Name2-Hexanone
DescriptionPresent in hop oil (Humulus lupulus), potato (Solanum tuberosum) and groundnuts (Arachis hypogaea) 2-Oxohexane is a volatile organic compound. 2-Oxohexane is occasionally found as a volatile component of normal human biofluids. 2-Oxohexane is an hexacarbon solvent; Hexan-2-one is the organic compound with the formula C4H9COCH3. This colorless to pale yellow liquid has a sharp odor. It is a ketone and often known either as MBK (methyl butyl ketone) or 2-hexanone. It dissolves very easily in water, and can evaporate easily into the air as a vapor. Hexan-2-one was used in the past in paint and paint thinner, to make other chemical substances, and to dissolve oils and waxes.; the neurotoxicity of hexacarbon solvents has become apparent and an extensive literature has already developed as a result of the clinical and epidemiological implications of the human disease. The main neurological disorders associated with chronic volatile substance are peripheral neuropathy, cerebellar disease, chronic encephalopathy and dementia. Apart from peripheral neuropathy, the clinical features are non-specific, evidence for solvent-related toxicity is in most cases circumstantial and there is no clear dose/response relationship. (PMID: 5556886, 6278344, 2550357). 2-Hexanone is found in many foods, some of which are nuts, cereals and cereal products, pepper (c. annuum), and cloves.

Classification
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.
