Metabolite Identification
Common Name3,3'-Dichlorobenzidine
Description3,3'-Dichlorobenzidine belongs to the class of organic compounds known as 3,3'-disubstituted benzidines. These are organic compounds containing a benzidine skeleton, which is substituted only at the 3- and 3'-positions. 3,3'-Dichlorobenzidine is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Based on a literature review very few articles have been published on 3,3'-Dichlorobenzidine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3,3'-dichlorobenzidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3,3'-Dichlorobenzidine 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.
