Calcifediol-¹³C₅ monohydrate  (Synonyms: 25-Hydroxy Vitamin D3-¹³C₅ monohydrate)

Calcifediol-¹³C₅ monohydrate is the ¹³C-labeled Calcifediol monohydrate. Calcifediol monohydrate (25-hydroxy Vitamin D3 monohydrate), is an effective VDR ligand and VD supplement. Calcifediol is a prohormone of the vitamin D endocrine system (VDES) and is hydroxylated in the liver to produce the active form, calcitriol. Calcifediol can rapidly increase serum VD levels^[1][2][3].

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].
