1-Butyl-2-methylpyridinium hexafluorophosphate, CAS: 1268986-44-2

Key Applications:

Electrochemical Systems

• Serves as a stable ionic liquid electrolyte component in supercapacitors and advanced battery research.
• Supports wide electrochemical windows and low volatility, enabling high‑temperature or high‑voltage device testing.
• Useful as a medium for electrodeposition studies where controlled ion mobility and low moisture sensitivity are required.

Catalysis and Synthesis

• Functions as a non‑volatile reaction medium for transition‑metal‑catalyzed transformations, particularly those benefiting from ionic environments.
• Employed in biphasic catalysis and recyclable solvent systems due to its thermal stability and low vapor pressure.
• Suitable for nucleophilic substitution and alkylation reactions where PF₆⁻ provides minimal coordinating interference.

Separation Science

• Utilized in ionic‑liquid‑modified stationary phases for chromatography, improving selectivity for polar and aromatic analytes.
• Acts as an extraction medium for metal ions and organic compounds in liquid–liquid extraction workflows.

Materials and Surface Science

• Incorporated into polymer–ionic liquid composites to enhance conductivity and mechanical performance.
• Used in thin‑film fabrication and surface modification studies where ionic liquids enable uniform deposition and tunable interfacial behavior.

Spectroscopy and Fundamental Research

• Provides a controlled, non‑aqueous environment for spectroscopic measurements of reactive or moisture‑sensitive species.
• Supports studies on ion pairing, solvation dynamics, and structure–property relationships in pyridinium‑based ionic liquids.
