Triadimenol-d4 is the deuterium labeled Triadimenol[1]. Triadimenol is a triazole fungicide and has been widely used in agriculture. Triadimenol has certain toxicity to animals[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].
