Quality Control

Our Quinine Citrate is manufactured and tested to meet stringent pharmacopeial standards, including USP and EP monographs where applicable. Every batch undergoes rigorous analytical testing for identity, potency, and purity. A comprehensive Certificate of Analysis (COA) detailing assay results, impurity profiles, and physical characteristics is provided to ensure full traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
