1,2-Dimethyl-3-propylimidazolium bis(trifluoromethylsulfonyl)imide, CAS: 169051-76-7

Key Applications

Electrochemical Systems

• Serves as a high‑stability ionic liquid electrolyte component for lithium, sodium, and multivalent metal batteries, benefiting from the TFSI⁻ anion’s wide electrochemical window and low coordinating character.
• Supports high‑temperature supercapacitor formulations where low volatility and strong thermal resilience are required.
• Functions as a conductive medium in redox‑flow and hybrid flow battery research, particularly where cation structure influences viscosity and ion mobility.

Catalysis and Synthesis

• Acts as a non‑volatile reaction medium for transition‑metal‑catalyzed transformations, including C–C and C–N coupling, hydrogenation, and selective oxidations.
• Provides a tunable solvent environment for organocatalysis, enabling enhanced selectivity and recyclability.
• Useful in biphasic catalysis where phase separation and catalyst retention are critical.

Materials Science and Polymer Processing

• Employed as a plasticizer or ionic additive in polymer electrolytes, ionogels, and high‑performance elastomers.
• Facilitates dispersion and stabilization of nanoparticles, carbon materials, and metal oxides due to its balanced polarity and low nucleophilicity.
• Supports surface modification and thin‑film deposition processes where ionic liquids enable controlled morphology and reduced defect formation.

Separation Science and Extraction

• Functions as an extraction medium for metal ions, hydrophobic organics, and fluorinated species, leveraging the hydrophobic TFSI⁻ anion.
• Enables selective partitioning in liquid–liquid extraction systems, particularly for rare‑earth and transition‑metal separations.
• Useful in gas absorption studies, including CO₂ capture, where cation substitution patterns influence solubility and transport.

Thermal and Chemical Stability Applications

• Suitable for high‑temperature lubrication and tribological studies where non‑flammability and thermal endurance are required.
• Serves as a stable medium for studying reaction kinetics under elevated temperatures or inert‑atmosphere conditions.
• Supports high‑vacuum and high‑temperature environments where conventional solvents degrade or volatilize.

Analytical and Spectroscopic Uses

• Provides a low‑volatility matrix for electrochemical impedance spectroscopy, NMR diffusion studies, and vibrational spectroscopy.
• Useful in calibrating ion transport models due to its well‑defined cation structure and predictable physicochemical behavior.
