Quality Control

Our 1-Butyl-1-Methylpyrrolidinium Tris(Pentafluoroethyl)Trifluorophosphate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing exact specifications for purity, water content, and halide impurities are provided with every shipment to support your R&D and production quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C to maintain long-term stability and minimize degradation. Keep away from strong acids and strong bases.
