Quality Control

Our 9-Diazo-9H-Fluorene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 stability. Keep away from heat, sparks, and open flame.
