Quality Control

Our 1-Butyl-3-Methylimidazolium Bis(Trifluoromethanesulfonyl)imide is produced under stringent 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, water content, and key impurity profiles are provided and available upon request, supporting compliance with research and industrial application standards.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry place at room temperature (15-25°C/59-77°F) under an inert atmosphere such as argon or nitrogen to prevent moisture absorption and degradation. Keep the container tightly sealed when not in use.
