Metabolite Identification
Common Name2-(p-Aminobenzamido)pyridine
Description2-(p-Aminobenzamido)pyridine, also known as carbopyridine, belongs to the class of organic compounds known as aminobenzoic acids and derivatives. These are benzoic acids (or derivative thereof) containing an amine group attached to the benzene moiety. Based on a literature review very few articles have been published on 2-(p-Aminobenzamido)pyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-(p-aminobenzamido)pyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-(p-Aminobenzamido)pyridine 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.
