Quality Control

Our 4,5-Dinitro-9H-Fluorene-2,7-Disulfonyl Dichloride, 97% is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the specified grade and consistency required for research and industrial synthesis. Certificates of Analysis (COA) detailing all critical parameters are available upon request to support your quality assurance and regulatory documentation 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 tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
