Quality Control

Our 1-Butyl-4-Methylpyridinium Bis(Trifluoromethylsulfonyl)Imide is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, Karl Fischer titration for water content, and NMR/IR for structural confirmation, to ensure it meets high-purity standards for research and industrial applications. Certificates of Analysis (COA) with detailed specifications are provided with every shipment.

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 material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong bases and fluorides.
