1-Methyl-3-octylimidazolium tetrafluoroborate, CAS: 244193-52-0

Key Applications:

Electrochemical Systems

• Serves as a stable, non‑volatile electrolyte component in supercapacitors, lithium‑free energy storage, and high‑temperature electrochemical devices.
• Offers wide electrochemical windows and low vapor pressure, supporting long‑term cycling stability.

Solvent for Organic Synthesis

• Functions as a tunable, non‑coordinating reaction medium for transition‑metal catalysis, nucleophilic substitutions, and oxidation reactions.
• Enhances reaction rates and selectivity in systems requiring hydrophobic ionic environments.

Extraction & Separation Processes

• Effective in liquid–liquid extraction of aromatic hydrocarbons, metal ions, and polar organics due to its hydrophobic cation and BF₄⁻ anion.
• Used in biphasic catalysis and ionic liquid–based separations where low miscibility with water is advantageous.

Surfactant & Self‑Assembly Studies

• Supports formation of micelles, vesicles, and other structured phases in colloidal systems.
• Utilized in research on interfacial behavior, nanostructured materials, and ionic‑liquid templating.

Materials Science & Nanomaterials

• Acts as a stabilizing medium for synthesizing metal nanoparticles, nanocomposites, and functional coatings.
• Provides controlled nucleation environments due to its high ionic strength and thermal stability.

Thermal & Chemical Stability Applications

• Suitable for high‑temperature lubrication, heat‑transfer fluids, and non‑flammable solvent systems.
• BF₄⁻ anion contributes to good thermal resistance and low volatility.
