Quality Control

Our 1,4-Bis(4-Aminophenoxy)-2-Phenylbenzene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to guarantee traceability and consistency.

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). This material is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve purity and prevent degradation. Keep away from strong oxidizing agents.
