1-Butyl-2-methylpyridinium triflate, CAS: 1770850-20-8

Key Applications:

Electrochemical Systems

• Serves as a stable ionic liquid electrolyte component with wide electrochemical windows.
• Supports ion transport in supercapacitors, redox‑flow systems, and specialty battery chemistries.
• Useful in electrodeposition studies where low volatility and controlled ion mobility are required.

Catalysis and Synthesis

• Functions as a non‑volatile reaction medium for acid‑catalyzed and transition‑metal‑catalyzed transformations.
• Enhances selectivity in electrophilic and nucleophilic substitution reactions due to its weakly coordinating triflate anion.
• Provides a tunable solvent environment for organometallic catalysis and biphasic reaction systems.

Materials Science

• Employed in polymer electrolyte formulations to improve ionic conductivity and thermal stability.
• Acts as a processing aid for ion‑conductive films, membranes, and specialty coatings.
• Supports the fabrication of ionic‑liquid‑modified nanoparticles and hybrid materials.

Separation Science

• Used as a stationary‑phase modifier in chromatography to adjust polarity and retention behavior.
• Enables selective extraction of metal ions and organic species in liquid–liquid or supported liquid membrane systems.

Thermal and Transport Studies

• Suitable for fundamental investigations of viscosity, conductivity, and ion‑pairing behavior in pyridinium‑based ionic liquids.
• Provides a model system for studying structure–property relationships in substituted pyridinium salts.
