Quality Control

Our 1-Butyl-1-Methylpyrrolidinium Trifluoromethanesulfonate 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 purity, water content, and halide content are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
