| Common Name | Thiophene-2-carboxylic acid |
|---|
| Description | thiophene-2-carboxylic acid, also known as 2-thiophenecarboxylate or 2-carboxythiophene, belongs to the class of organic compounds known as thiophene carboxylic acids. Thiophene carboxylic acids are compounds containing a thiophene ring which bears a carboxylic acid group. Based on a literature review very few articles have been published on thiophene-2-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 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 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. |
