1-Butyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide, CAS NO: 350493-08-2

Key Applications:

Electrochemical Applications

• High‑voltage electrolytes for lithium, sodium, and multivalent metal batteries, leveraging wide electrochemical windows and low flammability.
• Electrolyte additive or co‑solvent to improve SEI formation, ionic conductivity, and thermal stability in next‑generation cell chemistries.
• Supercapacitor electrolytes, particularly for high‑temperature or high‑power systems requiring low volatility and stable ion transport.
• Electrodeposition media for metals and alloys where controlled nucleation and smooth film formation are required.

Catalysis and Synthesis

• Non‑coordinating reaction medium for acid‑sensitive or moisture‑sensitive transformations due to the weakly coordinating TFSI⁻ anion.
• Phase‑transfer medium enabling enhanced solubility of organic substrates and transition‑metal complexes.
• Support for homogeneous and biphasic catalysis, especially in C–C coupling, hydrogenation, and oxidation systems.
• Stabilizing environment for reactive intermediates, benefiting mechanistic studies and high‑selectivity transformations.

Materials Science and Engineering

• Polymer electrolyte component for ion‑conducting membranes, gels, and solid‑state devices requiring high thermal stability.
• Plasticizer or ionic dopant in advanced polymers, improving conductivity and mechanical flexibility.
• Processing aid for nanomaterials, including dispersion of carbon nanotubes, graphene, and metal nanoparticles.
• Template or structuring medium in sol–gel and porous material synthesis where ionic liquids influence pore architecture.

Separation and Extraction

• Hydrophobic extraction phase for metal ions, organometallic species, and hydrophobic organics.
• Solvent for liquid–liquid extraction in systems requiring low miscibility with water and high chemical stability.
• Selective dissolution medium for fluorinated compounds, aromatic species, and specialty polymers.

Thermal and Chemical Stability Applications

• Heat‑transfer and thermal‑management fluids in niche systems requiring non‑volatile, thermally stable media.
• Lubrication and anti‑wear additives in extreme environments where conventional lubricants degrade.
• Stabilizing medium for high‑temperature spectroscopy, electrochemical testing, and reaction monitoring.

Analytical and Research Uses

• Electrochemical probe solvent for studying redox couples, ion pairing, and charge‑transfer kinetics.
• Medium for spectroscopic studies (NMR, IR, UV‑Vis) where low vapor pressure and chemical inertness are advantageous.
• Reference formulation component in benchmarking ionic liquid behavior across cation/anion families.
