Metabolite Identification
Common Name2-Methylhexane
Description2-Methylhexane, also known as heptanes, belongs to the class of organic compounds known as branched alkanes. These are acyclic branched hydrocarbons having the general formula CnH2n+2. Based on a literature review a significant number of articles have been published on 2-Methylhexane. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-methylhexane is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Methylhexane 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.
