Quality Control

Our 1,9-Diamino-9H-Fluorene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications 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 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. Keep away from heat, sparks, and open flame.
