Metabolite Identification

Common Name

4-Methyl-2-pentanol

Description

4-METHYL-2-PENTANOL, also known as isobutylmethylcarbinol, belongs to the class of organic compounds known as secondary alcohols. Secondary alcohols are compounds containing a secondary alcohol functional group, with the general structure HOC(R)(R') (R,R'=alkyl, aryl). 4-METHYL-2-PENTANOL is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-methyl-2-pentanol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Methyl-2-pentanol is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
