cholecalciferol and its Impurities
Cholecalciferol is a form of vitamin D which is naturally synthesized in skin and functions as a pro-hormone, being converted to calcitriol. It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system.. Reference standards of Cholecalciferol API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below
