Metabolite Identification
Common NameBenzoic acid, 2-(acetyloxy)-5-amino-
DescriptionBenzoic acid, 2-(acetyloxy)-5-amino-, also known as acetyl-5-asa or acetyl-5-aminosalicylic acid, belongs to the class of organic compounds known as acylsalicylic acids. These are o-acylated derivatives of salicylic acid. Based on a literature review very few articles have been published on Benzoic acid, 2-(acetyloxy)-5-amino-. This compound has been identified in human blood as reported by (PMID: 31557052 ). Benzoic acid, 2-(acetyloxy)-5-amino- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Benzoic acid, 2-(acetyloxy)-5-amino- 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.
