Pirimicarb-d6 is the deuterium labeled Diuron. Diuron is a phenylurea herbicide that inhibits photosynthesis by preventing the formation of ATP and NADH. Diuron (2,500 ppm, dietary) increases the incidence of urinary bladder urothelial carcinomas in male
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[75].
