Quality Control

Our Perphthalic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, potency, and stability. We provide full traceability and Certificates of Analysis (COA) are available for all shipments. Our quality commitment aligns with cGMP principles where applicable, ensuring reliability for critical industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its properties as a strong oxidizer and being easily oxidized, it is recommended to store under an inert atmosphere and separate from incompatible materials such as reducing agents, strong acids, and organic solvents. Recommended storage temperature is 2-8°C for extended stability.
