Metabolite Identification
Common NameMonoethyl phthalate
DescriptionMonoethyl phthalate, also known as metp, belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Monoethyl phthalate is an extremely weak basic (essentially neutral) compound (based on its pKa). Monoethyl phthalate is a potentially toxic compound. A phthalic acid monoester resulting from the condensation of one of the carboxy groups of phthalic acid with ethanol.
