  • Applications

    Quinidine sulfate anhydrous (CAS 50-54-4) is a cinchona alkaloid mainly used as an active pharmaceutical ingredient for antiarrhythmic therapy (class IA). The sulfate salt improves water solubility and is commonly employed in the formulation and manufacturing of drug products. In chemical synthesis, it is frequently used as a chiral resolving agent in asymmetric synthesis and as a scaffold for developing cinchona alkaloid derivatives. It may also serve in research and development contexts for pharmacology and analytical studies, subject to local regulations and formulation limits.
