Quality Control

Our 1‐Butyl‐1‐Methylpyrrolidinium Tricyanomethanide is produced under strict quality management protocols. 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 impurities are provided with every shipment to support your R&D and quality assurance requirements.

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) and must be kept under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Keep away from strong oxidizing agents.
