Mono(5-carboxy-2-ethylpentyl) phthalate-d₄  (Synonyms: MECPP-d₄)

Mono(5-carboxy-2-ethylpentyl) phthalate-d₄ (MECPP-d₄) is a deuterium labeled Mono(5-carboxy-2-ethylpentyl) phthalate (HY-133675). 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][3].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
