Metabolite Identification
Common Name5,5'-Dithiobis(2-nitrobenzoic acid)
Description5,5'-Dithiobis(2-nitrobenzoic acid), also known as ellman's reagent or DTNB, belongs to the class of organic compounds known as nitrobenzoic acids and derivatives. Nitrobenzoic acids and derivatives are compounds containing a nitrobenzoic acid moiety, which consists of a benzene ring bearing both a carboxylic acid group and a nitro group on two different ring carbon atoms. Based on a literature review a small amount of articles have been published on 5,5'-Dithiobis(2-nitrobenzoic acid). This compound has been identified in human blood as reported by (PMID: 31557052 ). 5,5'-dithiobis(2-nitrobenzoic acid) is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5,5'-Dithiobis(2-nitrobenzoic acid) 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.
