Benzo[a]pyrene-d₁₂ is the deuterium labeled Benzo[a]pyrene[1]. Benzo[a]pyrene shows lung carcinogenicity in animal models, and it is frequently used in chemoprevention studies[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].

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