1-Ethylpyridinium triflate, CAS: 3878-80-6

Key Applications:

• Electrolyte and Ionic Conductor Development

Used as a high‑conductivity ionic component in non‑aqueous electrolyte systems, particularly where thermal stability and low volatility are required. Its triflate anion supports stable ion transport in electrochemical devices, sensors, and prototype energy‑storage materials.

• Catalysis and Organic Synthesis

Functions as a non‑nucleophilic ionic medium or co‑catalyst in acid‑promoted transformations, including alkylations, rearrangements, and dehydrative processes. The pyridinium cation provides tunable polarity for reaction optimization.

• Solvent and Reaction Medium

Employed as a polar, thermally robust ionic liquid for challenging synthetic environments. Its combination of pyridinium structure and triflate counterion enables enhanced solvation of organometallic species, transition‑metal complexes, and reactive intermediates.

• Materials Science and Polymer Processing

Incorporated into polymer matrices to adjust conductivity, mechanical properties, and ion‑transport behavior. Suitable for exploratory work in ion‑gel formation, membrane development, and advanced composite materials.

• Analytical and Spectroscopic Applications

Used as a stable ionic reference medium or dispersant in spectroscopic studies requiring low nucleophilicity and high thermal tolerance. Supports sample preparation for NMR, IR, and electroanalytical methods.

• Surface and Interface Engineering

Applied in thin‑film deposition, surface modification, and interfacial studies where controlled ionic environments are needed. The triflate anion contributes to predictable surface interactions and low residue formation.
