Metabolite Identification
Common Name2,4-Dinitrophenylhydrazine
Description2,4-Dinitrophenylhydrazine, also known as 1-hydrazino-2,4-dinitrobenzene or 2,4-DNP hydrazine, belongs to the class of organic compounds known as nitrobenzenes. Nitrobenzenes are compounds containing a nitrobenzene moiety, which consists of a benzene ring with a carbon bearing a nitro group. Based on a literature review very few articles have been published on 2,4-Dinitrophenylhydrazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,4-dinitrophenylhydrazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,4-Dinitrophenylhydrazine 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.
