Quality Control

Our Perfluoro(2-Ethoxyethane)Sulfonyl Fluoride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC, and FTIR, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment, ensuring full traceability and compliance with your internal quality standards and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong bases and incompatible materials.
