4027 Monoethylhexyl phthalic acid Monoethylhexyl phthalic acid (MEHP) is an active metabolite of Bis(2-ethylhexyl)phthalate (DEHP). DEHP measured from the blood of pregnant women have been significantly associated with the decreased penis width, shorter anogenital distance, and the incomplete descent of testes of their newborn sons, replicating effects identified in animals. DEHP hydrolyzes to MEHP via the enzyme Bis(2-ethylhexyl)phthalate acylhydrolase(3.1.1.60)and subsequently to phthalate salts. The released alcohol is susceptible to oxidation to the aldehyde and carboxylic acid. 4376-20-9 20393 C16H22O4 White powder.
