Quality Control

Our 2-Bromo-1,1,2,2-Tetrafluoroethyl Chlorosulfate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including NMR, HPLC, and GC to confirm identity and potency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use. Recommended long-term storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
