Common Name2-Heptanone
Description2-Heptanone, also known as butylacetone or heptan-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. Thus, 2-heptanone is considered to be an oxygenated hydrocarbon lipid molecule. 2-Heptanone is a ketone with the molecular formula C7H14O. 2-Heptanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2-Heptanone exists in all living species, ranging from bacteria to humans. 2-Heptanone is a sweet, cinnamon, and coconut tasting compound. 2-Heptanone is found, on average, in the highest concentration within a few different foods, such as corns, cow milk, and peppermints. 2-Heptanone has also been detected, but not quantified in several different foods, such as tarragons, blackberries, tortilla chips, ceylon cinnamons, and evergreen blackberries. 2-Heptanone is one of the metabolites of n-heptane found in the urine of employees exposed to heptane in shoe and tire factories. 2-Heptanone, with regard to humans, has been found to be associated with several diseases such as ulcerative colitis, nonalcoholic fatty liver disease, crohn's disease, and hepatic encephalopathy; 2-heptanone has also been linked to the inborn metabolic disorder celiac disease. It is a colorless to white liquid with a banana-like, fruity odor.
