Metabolite Identification
Common Name2,1,3-Benzoxadiazole-4-sulfonic acid, 7-fluoro-
Description7-fluoro-2,1,3-benzoxadiazole-4-sulfonic acid belongs to the class of organic compounds known as benzoxadiazoles. These are organic compounds containing a benzene fused to an oxadiazole ring (a five-membered ring with two carbon atoms, one nitrogen atom, and one oxygen atom). Based on a literature review a significant number of articles have been published on 7-fluoro-2,1,3-benzoxadiazole-4-sulfonic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,1,3-benzoxadiazole-4-sulfonic acid, 7-fluoro- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,1,3-Benzoxadiazole-4-sulfonic acid, 7-fluoro- 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.
