Metabolite Identification
Common Name2,2'-Bithiophene
Description2,2'-Bithiophene, also known as 2,2'-dithienyl or alpha-bithiophene, belongs to the class of organic compounds known as bi- and oligothiophenes. These are organic compounds containing two or more linked thiophene rings. Thiophene is a five-member aromatic ring with one sulfur and four carbon atoms. Thus, 2,2'-bithiophene is considered to be an oxygenated hydrocarbon. Based on a literature review very few articles have been published on 2,2'-Bithiophene. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,2'-bithiophene is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,2'-Bithiophene 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.
