Metabolite Identification
Common NameN-Hydroxybenzamide
DescriptionBenzhydroxamic Acid, also known as benzhydroxamate, belongs to the class of organic compounds known as benzoic acids and derivatives. These are organic compounds containing a carboxylic acid substituent attached to a benzene ring. Benzhydroxamic 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-hydroxybenzamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-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.
