Quality Control

Our production of Ethanesulfonyl Fluoride, 1,1,2,2-Tetrafluoro-2-[(Trifluoroethenyl)Oxy]- adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. 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. Recommended long-term storage temperature is 2-8°C (refrigerated).
