Metabolite Identification

Common Name

Furazan

Description

Furazan belongs to the class of organic compounds known as furazans. Furazans are compounds containing a furazan moiety, which consists of a five-membered aromatic ring with 1 oxygen and 2 nitrogen atoms at positions 2, 1, and 5, respectively. Based on a literature review a significant number of articles have been published on Furazan. This compound has been identified in human blood as reported by (PMID: 31557052 ). Furazan is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Furazan 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.
