Quality Control

Our 3,5-Dichloro-4-Fluorobenzenesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with customer specifications and industry 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 material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong bases, oxidizing agents, and moisture.
