Quality Control

Our 4,5-Dinitro-9-Oxo-9H-Fluorene-2,7-Disulfonyl Dichloride, 97% is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques like HPLC and NMR to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment, supporting your quality assurance and regulatory compliance 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 hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong acids and incompatible materials.
