Common NameDimethyl phthalate
DescriptionDimethylphthalate belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Phthalate esters are endocrine disruptors. Dimethylphthalate is an extremely weak basic (essentially neutral) compound (based on its pKa). The terminal or next-to-last carbon atom in the monoester can also be oxidized to an alcohol, which can be excreted as is or first oxidized to an aldehyde, ketone, or carboxylic acid. Dimethylphthalate is a potentially toxic compound. Phthalate esters are esters of phthalic acid and are mainly used as plasticizers, primarily used to soften polyvinyl chloride. They decrease foetal testis testosterone production and reduce the expression of steroidogenic genes by decreasing mRNA expression. Phthalates are hazardous due to their ability to act as endocrine disruptors. The combination of effects associated with phthalates is called 'phthalate syndrome’. Phthalate esters are first hydrolyzed to their monoester derivative. This compound has been identified in human blood as reported by (PMID: 31557052 ). Dimethyl phthalate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Dimethyl phthalate 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.
