Common Name | 5-Methylheptan-3-one |
---|
Description | 5-methylheptan-3-one 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, 5-methylheptan-3-one is considered to be an oxygenated hydrocarbon lipid molecule. 5-methylheptan-3-one is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 5-methylheptan-3-one can be found in peppermint, which makes 5-methylheptan-3-one a potential biomarker for the consumption of this food product. |
