Pharmaceutical-grade Chloroquine Phosphate (CAS 50-63-5) supplied wholesale by Zyntex to licensed producers. 4-Aminoquinoline antimalarial API for tablets, syrups and injections. CoA and SDS with every lot.
Chloroquine phosphate (C18H26ClN3·2H3PO4) is a white to off-white crystalline powder that dissolves freely in water and tastes very bitter. Doses usually refer to the chloroquine base content.
Pharmaceutical companies use it in tablets, syrups and injections for malaria in regions where parasites remain sensitive, as well as for amoebic liver infections. Similarly, related antimalarials in our range include Hydroxychloroquine Sulfate, Artesunate and Quinine Sulfate. Ornamental fish producers also use it in some aquarium treatments.
Because chloroquine has a narrow safety margin, overdose is dangerous, so dosing requires care. Zyntex supplies chloroquine phosphate only to licensed pharmaceutical and veterinary companies.
Typical uses include, for example:
💊 Tablets
API for antimalarial tablets.
🥄 Syrups

💉 Injections
API for injectable formulations.
