Quality Control

Our Arbidol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure compliance with pharmaceutical-grade standards. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specified parameters. Our quality commitment supports applications requiring GMP compliance and reliable supply chain documentation.

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 each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
