Quality Control

Our production of 3,5-Dichloro-2-Fluorobenzenesulfonyl Chloride adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure high purity and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, documenting all critical parameters. Our quality system is designed to meet the rigorous standards required for cGMP and non-GMP applications in research and development.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
