Quality Control

Our 9,9-Bis(4-Aminophenyl)Fluorene 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 specifications for high-performance polymer applications. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 sensitivity to light and tendency for oxidation, 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 heat, sparks, and open flame.
