Quality Control

Our 1,1-Diphenyl-2,2-Di(4-Aminobiphenyl)Ethylene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification, to ensure it meets exacting R&D and production standards. Certificates of Analysis (COA) with detailed specifications are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
