Allotetrahydrocortisol-d5 is the deuterium labeled Allotetrahydrocortisol. Allotetrahydrocortisol (5a-Tetrahydrocortisol) is a metabolite of Cortisol. Cortisol is the main glucocorticoid in human. It is produced in adrenal cortex and plays a crucial role in many physiological processes^[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].
