Isoprothiolane-d4 is the deuterium labeled Isoprothiolane. Isoprothiolane is a systemic fungicide. Isoprothiolane is a rice blast controlling agent against the fungal disease of rice plantyPyvioutavia oryzaeCav[1][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].
