Quality Control

Our 2,2'-Bis(4-Aminophenoxy)Biphenyl 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 polymer synthesis. Certificates of Analysis (COA) detailing purity, moisture content, and other critical parameters are provided with every shipment to guarantee supply reliability and batch-to-batch consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
