Quality Control

Our 1,1,2,2,3,3-Hexafluoropropane-1,3-Disulfonimide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided to guarantee compliance with your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption. Recommended long-term storage temperature is 2-8°C.
