Quality Control

Our Potassium Cyclopropyltrifluoroborate is manufactured under strict quality control protocols to meet the exacting standards of research and production. Each batch is analyzed using advanced techniques including NMR (¹H, ¹¹B, ¹³C) and HPLC to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure full traceability and compliance with your internal quality systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, this material should be handled under an inert atmosphere (argon or nitrogen) in a moisture-controlled environment such as a glovebox to maintain stability and prevent decomposition. Recommended long-term storage temperature is 2-8°C.
