Metabolite Identification
Common NameN-Acetyl-2-hydroxybenzamide
DescriptionN-(2-hydroxybenzoyl)ethanimidic acid 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. N-(2-hydroxybenzoyl)ethanimidic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). N-acetyl-2-hydroxybenzamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Acetyl-2-hydroxybenzamide 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.
