Metabolite Identification

Common Name

2-(Hexyloxy)ethanol

Description

2-(Hexyloxy)ethanol, also known as EGHE, belongs to the class of organic compounds known as dialkyl ethers. These are organic compounds containing the dialkyl ether functional group, with the formula ROR', where R and R' are alkyl groups. Based on a literature review very few articles have been published on 2-(Hexyloxy)ethanol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-(hexyloxy)ethanol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-(Hexyloxy)ethanol 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.
