1-Butyl-4-methylpyridinium tetrafluoroborate, CAS: 34952-33-0

Key Applications:

Electrochemical Systems

• Serves as a stable, non‑volatile electrolyte component for supercapacitors and advanced battery chemistries.
• Enhances ionic conductivity and electrochemical window in redox‑active systems.
• Used in electrodeposition studies where controlled ion mobility and low vapor pressure are required.

Catalysis & Organic Synthesis

• Functions as a tunable reaction medium for acid‑ and base‑catalyzed transformations.
• Supports transition‑metal catalysis by improving catalyst dispersion and enabling biphasic separation.
• Applied in alkylation, oxidation, and coupling reactions where ionic liquids improve selectivity and yield.

Separation Science & Extraction

• Employed as a task‑specific solvent for liquid–liquid extraction of metal ions, dyes, and organic contaminants.
• Useful in biphasic catalytic systems and solvent‑swap processes due to its thermal stability and low miscibility with non‑polar phases.
• Supports chromatographic method development as a mobile‑phase additive to modulate retention and peak shape.

Materials Science & Polymer Processing

• Acts as a plasticizing and structuring agent in polymer electrolytes and ion‑conducting films.
• Used to tune morphology and ionic transport in block copolymers and hybrid organic–inorganic materials.
• Facilitates nanoparticle dispersion and surface modification due to its ionic environment and low volatility.

Thermal & Transport Property Studies

• Serves as a model ionic liquid for investigating viscosity, conductivity, and ion‑pairing behavior.
• Used in simulation‑validated experimental studies on solvation dynamics and ion transport mechanisms.

Green Chemistry & Process Intensification

• Enables solvent reduction and recyclability in multi‑step synthetic workflows.
• Supports greener reaction conditions by replacing volatile organic solvents in bench‑scale and pilot‑scale processes.
