Quality Control

Our 1-Butyl-1-Methylpyrrolidinium Hexafluorophosphate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and ion chromatography, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, moisture content, and halide impurities are provided with every shipment to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) after opening to prevent moisture absorption and decomposition.
