Metabolite Identification
Common NameBenfluorex
DescriptionBenfluorex, also known as mediaxal, belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Based on a literature review a significant number of articles have been published on Benfluorex. This compound has been identified in human blood as reported by (PMID: 31557052 ). Benfluorex is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Benfluorex 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.
