Mono(5-carboxy-2-ethylpentyl) phthalate

Mono(5-carboxy-2-ethylpentyl) phthalate (MECPP) is a metabolite of Di-(2-ethylhexyl) phthalate (DEHP). Di(2-ethylhexyl) phthalate is the predominant plasticizer added to rigid polyvinyl chloride (PVC) to impart flexibility, temperature tolerance, optical clarity, strength and resistance to kinking[1][2].
