Quality Control

Our 4-(Chlorosulfonyl)-4''-(Trifluoromethyl)Diphenyl Ether is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure the minimum 97% purity and identity are met. A detailed Certificate of Analysis (COA) documenting purity, impurities, and physical characteristics is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 degradation. Keep away from strong bases and oxidizing agents.
