Quality Control

Our 1-Butyl-2-Methylpyridinium Tetrafluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and ion chromatography, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your research and production specifications.

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); containers must be kept tightly sealed and under an inert atmosphere such as nitrogen or argon for long-term storage to prevent moisture absorption and decomposition.
