Quality Control

Our 1,3-Bis(3-Hydro-4-Aminophenoxy)-Benzene 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. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled 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.
