Metabolite Identification
Common Name2-Ethoxy-2-methylpropane
Descriptiontert-butyl ethyl ether, also known as 2-methyl-2-ethoxypropane or ETBE, 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 a significant number of articles have been published on tert-butyl ethyl ether. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-ethoxy-2-methylpropane is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Ethoxy-2-methylpropane 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.
