Quality Control

Our 2-[2-(Allyloxy)-1,1,2,2-Tetrafluoroethoxy]Tetrafluoroethansulfonyl Fluoride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, GC, and HPLC, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support custom synthesis and can tailor purity grades, including research and development (R&D) or commercial scale, to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile and strong acid/organic solvent nature, containers must be kept tightly sealed and away from heat, sparks, and open flames. Handle and store under an inert atmosphere such as nitrogen or argon to ensure long-term stability.
