Quality Control

Every batch of Fluoren-9-One-2,7-Disulfonyl Chloride is manufactured and tested under strict quality management protocols. We ensure high purity and consistency through comprehensive analytical methods including HPLC, NMR, and titration. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. Our quality system supports cGMP and ISO standards for reliable supply to regulated industries.

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 bases and moisture.
