Quality Control

Our 1-Butylpyridinium Bis(Trifluoromethylsulfonyl)Imide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to confirm identity, purity, and moisture content. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to ensure compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress.
