Quality Control

Our 1-Butyl-3-Methylpyridinium Bis(Trifluoromethylsulfonyl)imide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and water content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) for critical applications to prevent water absorption.
