11-Deoxycortisol-2,3,4-13C3 solution

An internal standard for 11-deoxycortisol, also known as cortodoxone. An immediate precursor to cortisol, 11-deoxycortisol is measured in whole blood by LC-MS/MS for newborn screening of congenital adrenal hyperplasia (CAH) and in serum or plasma

Biochem/physiol Actions 16-Dehydropregnenolone acetate (DPA) is synthesized from steroids sapogenin, diosgenin and solasodine. 16-Dehydropregnenolone acetate (DPA) is a crucial intermediate for the synthesis of steroid hormones-based drugs.
