Common Name | 2-Octanone |
---|
Description | 2-Octanone, also known as octan-2-one or fema 2802, 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-octanone is considered to be an oxygenated hydrocarbon lipid molecule. 2-Octanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2-Octanone is a bitter, earthy, and gasoline tasting compound. 2-Octanone has been detected, but not quantified, in several different foods, such as tortilla chips, cloves, tea, corns, and pomes. This could make 2-octanone a potential biomarker for the consumption of these foods. A methyl ketone that is octane substituted by an oxo group at position 2. |
