Quality Control

Our Potassium 4-Aminosalicylate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to guarantee traceability and compliance.

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). Due to its light-sensitive nature and tendency to be easily oxidized, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain product integrity.
