Metabolite Identification
Common NameBenzo[b]thiophene-2-carboxylic acid
DescriptionBenzo[b]thiophene-2-carboxylic acid belongs to the class of organic compounds known as 1-benzothiophenes. These are aromatic heterocyclic compound containing the Benzo[b]thiophene ring system. Based on a literature review a small amount of articles have been published on Benzo[b]thiophene-2-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Benzo[b]thiophene-2-carboxylic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Benzo[b]thiophene-2-carboxylic acid 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.
