Quality Control

Our 4,5-Diamino-9H-Fluoren-9-One is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your specifications and relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 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.
