Quality Control

Our Hedaquinium Chloride is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and potency. A Certificate of Analysis (COA) documenting results for assay, related substances, residual solvents, and microbiological quality is provided with each shipment. Production can be aligned with cGMP guidelines for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from strong oxidizing agents and incompatible materials. The product is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use to prevent absorption of atmospheric moisture.
