Quality Control

Our 5-Bromo-2-Fluorobenzenesulphonyl Chloride 98% is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the specified 98% minimum assay. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after opening to prevent decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
