Quality Control

Our p-(p-Anilinoanilino)Phenol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and melting point determination, to ensure it meets exacting standards. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance.

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 an inert atmosphere (e.g., nitrogen) to maintain optimal purity and stability. Keep away from strong oxidizing agents.
