Metabolite Identification
Common NameChlorthal-dimethyl
DescriptionChlorthal-dimethyl, also known as DCPA or dacthal, belongs to the class of organic compounds known as p-phthalate esters. These are ester derivatives of p-phthalic acids, which are based on a benzene 1,4-dicarboxylic acid skeleton. Chlorthal-dimethyl is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Chlorthal-dimethyl is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Chlorthal-dimethyl 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.
