1-Ethylimidazolium triflate, CAS: 501693-46-5

Key Applications:

Catalysis and Organic Synthesis

• Serves as a non‑volatile, thermally stable medium for acid‑catalyzed reactions.
• Supports esterification, alkylation, and dehydration processes where a strong, non‑nucleophilic anion is advantageous.
• Useful as a solvent or co‑solvent for transition‑metal catalysis due to its high ionic conductivity and low coordinating behavior.

Electrochemistry and Energy Materials

• Functions as an electrolyte component in electrochemical cells, particularly where wide electrochemical windows and low vapor pressure are required.
• Enhances ion transport in redox systems and can be blended with other ionic liquids to tune viscosity and conductivity.

Materials Science and Polymer Processing

• Acts as a processing aid for polymer dissolution, modification, and ion‑exchange functionalization.
• Enables controlled incorporation of ionic domains into polymer matrices for membranes, ionogels, and specialty coatings.

Separation Science

• Supports selective extraction of metal ions, organic compounds, and catalytic species due to its tunable polarity and thermal stability.
• Useful in biphasic systems where immiscibility with nonpolar solvents facilitates product recovery.

Spectroscopy and Analytical Chemistry

• Provides a stable, low‑volatility medium for NMR, IR, and electroanalytical studies.
• Reduces background interference in systems requiring non‑coordinating anions.

Green Chemistry and Process Intensification

• Replaces volatile organic solvents in high‑temperature or moisture‑sensitive reactions.
• Enables solvent recycling and reduced emissions in closed‑loop processes.
