Metabolite Identification
Common Name2,5-Dihydroxybenzamide
Description2,5-Dihydroxybenzamide, also known as gentisamide, belongs to the class of organic compounds known as salicylamides. These are carboxamide derivatives of salicylic acid. Salicylic acid is the ortho-hydroxylated derivative of benzoic acid. Based on a literature review a small amount of articles have been published on 2,5-Dihydroxybenzamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,5-dihydroxybenzamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,5-Dihydroxybenzamide 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.
