Quality Control

Our 3,3',4,4',5,5',6,6'-Octafluorobiphenyl-2,2'-Diamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for advanced material synthesis. Certificates of Analysis (COA) detailing purity, impurity profiles, and physical characteristics are provided with every shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature, the container should be opaque or stored in dark conditions. Keep away from strong oxidizing agents and incompatible materials.
