Quality Control

Our Biphenyl-3,3',5,5'-Tetracarboxylic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment, ensuring full traceability and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the product must be stored in a cool, dry place, ideally at 15-25°C, and under an inert atmosphere for long-term storage to prevent moisture absorption and potential degradation. Keep the container tightly sealed when not in use.
