Quality Control

Our n-Propyl-3-Methylpyridinium Bis(Trifluoromethylsulfonyl)Imide is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure the 99% minimum purity and low levels of halide and water impurities. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to guarantee traceability and batch-to-batch consistency for your critical R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the product should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is between 2°C and 8°C. Allow the container to reach room temperature before opening to prevent moisture condensation.
