Quality Control

Our 1-N,1-N,4-N,4-n-Tetrakis(4-Phenylphenyl)Benzene-1,4-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 exacting standards for advanced material synthesis. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 15-25°C. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
