1-Butyl-4-methylpyridinium triflate, CAS: 882172-79-4

Key Applications:

Electrochemical Systems

• Ionic liquid electrolyte component for supercapacitors, electrochemical sensors, and low‑voltage devices.
• Triflate anion supports wide electrochemical windows, low nucleophilicity, and stable ion transport.

Catalysis and Organic Synthesis

• Non‑volatile reaction medium for acid‑catalyzed and transition‑metal‑catalyzed transformations.
• Effective in Friedel–Crafts, esterification, and alkylation reactions requiring a polar, thermally robust solvent.

Separation Science

• Tunable solvent phase for liquid–liquid extraction of metal ions and polar organic compounds.
• Exhibits favorable phase behavior and low miscibility with nonpolar solvents.

Thermal and Process Fluids

• High thermal stability and negligible vapor pressure enable use in heat‑transfer media, thermal storage, and high‑temperature reaction environments.

Materials and Polymer Processing

• Processing aid or dopant for conductive polymers such as PEDOT and polyaniline.
• Enhances ionic conductivity and mechanical flexibility in ion‑gels and polymer electrolyte formulations.

Analytical Chemistry

• Additive in mass spectrometry and chromatographic methods to improve ionization efficiency and separation of polar analytes.
