Description

1-Butyl-3-methylimidazolium hexafluorophosphate (BMIMPF6) is a high-purity ionic liquid with the molecular formula C₈H₁₅F₆N₂P and CAS number 174501-64-5. This hydrophobic, air- and moisture-stable compound is widely utilized in electrochemical applications, catalysis, and material science due to its excellent thermal stability, low viscosity, and high ionic conductivity. BMIMPF6 is synthesized under stringent quality control to ensure minimal impurities, making it ideal for sensitive research applications. Its non-volatile nature and wide electrochemical window (-2.1 to +2.3 V vs. Ag/Ag⁺) render it a preferred electrolyte in supercapacitors, lithium-ion batteries, and electrodeposition processes. Packaged in amber glass bottles under inert gas to prevent degradation, this product is suitable for both industrial and academic laboratories.
