Benzyl cinnamate-d5 is the deuterium labeled Benzyl cinnamate[1]. Benzyl cinnamate, occurs in Balsam of Peru and Tolu balsam, in Sumatra and Penang benzoin, and as the main constituent of copaiba balsam, is used in heavy oriental perfumes and as a fixative[2].
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].
