Metabolite Identification
Common Name4,4'-Methylenebis(2-chloroaniline)
Description4,4'-Methylenebis(2-chloroaniline), also known as MOCA, belongs to the class of organic compounds known as diphenylmethanes. Diphenylmethanes are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. 4,4'-Methylenebis(2-chloroaniline) is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. 4,4'-Methylenebis(2-chloroaniline) is formally rated as a carcinogen (by IARC 1) and is also a potentially toxic compound. Based on a literature review a small amount of articles have been published on 4,4'-Methylenebis(2-chloroaniline). This compound has been identified in human blood as reported by (PMID: 31557052 ). 4,4'-methylenebis(2-chloroaniline) is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4,4'-Methylenebis(2-chloroaniline) 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.
