1-Butyl-3-methylpyridinium triflate, CAS: 857841-32-8

Key Applications:

Electrochemical Systems

• Serves as a stable ionic medium for electrochemical studies requiring wide electrochemical windows and low volatility.
• Supports ion transport in prototype electrolytes for capacitors, redox systems, and electrodeposition research.
• Useful in evaluating ionic‑liquid–based interfaces due to its thermal stability and predictable conductivity profile.

Catalysis and Organic Synthesis

• Functions as a non‑volatile reaction medium for acid‑catalyzed and transition‑metal‑catalyzed transformations.
• Provides enhanced solvation for polar intermediates, enabling rate improvements in selected coupling, alkylation, and rearrangement reactions.
• Suitable for biphasic catalysis where phase separation and product recovery are important.

Materials Science and Polymer Processing

• Acts as a processing aid or plasticizing ionic component in polymer blends, ionogels, and hybrid materials.
• Supports the formation of conductive films and membranes where ionic mobility and thermal robustness are required.
• Enables dispersion and stabilization of nanoparticles in non‑aqueous matrices.

Separation Science

• Employed as a tunable solvent or co‑solvent in liquid–liquid extraction systems targeting metal ions, organics, and specialty analytes.
• Useful in chromatographic method development where ionic‑liquid additives improve peak shape, selectivity, or retention control.

Thermal and Transport Studies

• Provides a model system for studying ion–ion and ion–solvent interactions due to its well‑defined cation/anion pairing.
• Used in research on viscosity, conductivity, and diffusion behavior of pyridinium‑based ionic liquids.

Specialty Applications

• Supports development of ionic‑liquid–based lubricants and anti‑wear additives for high‑temperature environments.
• Investigated in CO₂ capture and gas‑solvation studies where triflate‑based ionic liquids offer predictable physicochemical behavior.
