Quality Control

Our Tetraethylammonium Tris(trifluoromethylsulfonyl) Methide 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 consistent performance. Certificates of Analysis (COA) detailing purity, moisture content, and key impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and should be stored in a cool, dry place, ideally under an inert atmosphere such as argon or nitrogen to prevent moisture uptake. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize condensation.
