Metabolite Identification
Common Name1,2-Benzisoxazole
Description1,2-Benzisoxazole, also known as benz(D)isoxazole or indoxazene, belongs to the class of organic compounds known as benzisoxazoles. These are aromatic compounds containing a benzene ring fused to an isoxazole ring. Isoxazole is five-membered ring with three carbon atoms, and an oxygen atom next to a nitrogen atom. Based on a literature review very few articles have been published on 1,2-Benzisoxazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2-benzisoxazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2-Benzisoxazole 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.
