Quality Control

Our N,N'-Bis(3-Methylphenyl)-(1,1'-Biphenyl)-4,4'-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 applications. Certificates of Analysis (COA) documenting purity, related substances, and physical properties are available for every shipment.

Storage

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