1-Ethyl-1-methylpyrrolidinium tetrafluoroborate, CAS: 117947-85-0

Key Applications:

Electrochemical Systems

• Employed as a high‑conductivity electrolyte in supercapacitors, redox‑flow systems, and next‑generation batteries.
• Supports stable electrode interfaces due to its wide electrochemical window and low flammability.
• Used in electrodeposition of metals and alloys, enabling smooth, uniform coatings under water‑free conditions.

Catalysis & Synthesis

• Functions as a non‑volatile reaction medium for organic and organometallic transformations requiring controlled polarity.
• Enhances selectivity and yield in transition‑metal‑catalyzed reactions by stabilizing reactive intermediates.
• Serves as a phase‑transfer medium for biphasic catalytic systems.

Materials Processing

• Utilized in nanomaterial dispersion and stabilization, particularly for carbon nanostructures and metal nanoparticles.
• Acts as a templating or structuring agent in polymer and porous‑material synthesis.
• Supports ionic‑liquid‑assisted sol–gel processes for advanced ceramics and hybrid materials.

Thermal & Chemical Stability Applications

• Suitable for high‑temperature lubrication and anti‑wear formulations where volatility must be minimized.
• Used in heat‑transfer and thermal‑management fluids requiring ionic conductivity and chemical inertness.
• Provides a stable medium for gas absorption studies, including CO₂ and SO₂ capture research.

Separation & Extraction

• Applied in liquid–liquid extraction of metal ions, aromatic hydrocarbons, and polar organics.
• Supports selective dissolution of biomass components (cellulose, lignin) in pretreatment workflows.
• Enables ionic‑liquid‑based chromatography and membrane‑separation research.
