Metabolite Identification
Common Name9-Fluorenylmethyl carbazate
Description9-Fluorenylmethyl carbazate, also known as fmoc-hydrazine, belongs to the class of organic compounds known as fluorenes. Fluorenes are compounds containing a fluorene moiety, which consists of two benzene rings connected through either a cyclopentane, cyclopentene, or cyclopenta-1,3-diene. Based on a literature review very few articles have been published on 9-Fluorenylmethyl carbazate. This compound has been identified in human blood as reported by (PMID: 31557052 ). 9-fluorenylmethyl carbazate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 9-Fluorenylmethyl carbazate 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.
