USP-grade Prednisone (CAS 53-03-2), 98–102%, supplied wholesale by Zyntex to licensed producers. Corticosteroid API for tablets and oral solutions. CoA and SDS with every lot.
Prednisone (C21H26O5) is a white to practically white crystalline powder that is very slightly soluble in water. It is a prodrug that the liver converts into its active form, Prednisolone.
In addition, pharmaceutical companies use it in tablets of 1 to 50 mg and in oral solutions for inflammatory and immune conditions. It is on the WHO Model List of Essential Medicines. Similarly, other corticosteroid APIs in our range include Dexamethasone and Hydrocortisone.
Because corticosteroids are potent, handling requires dust control. Zyntex therefore supplies it from qualified API producers, only to licensed pharmaceutical companies.
