1-Methyl-1-propylpyrrolidinium hexafluorophosphate, CAS: 327022-58-2

Key Applications:

Electrochemical Systems & Energy Storage

• Employed as a non‑aqueous electrolyte component in supercapacitors and high‑voltage electrochemical cells requiring wide electrochemical windows.
• Used to formulate ionic‑liquid‑based electrolytes with enhanced thermal stability and reduced volatility for next‑generation battery research.
• Serves as a conductivity‑enhancing additive in redox‑active organic systems and ionic‑liquid‑gel polymer electrolytes.

Solvent & Extraction Applications

• Functions as a hydrophobic extraction medium for metal ions, organometallic complexes, and hydrophobic organic solutes.
• Applied in liquid–liquid extraction systems where PF₆⁻ ionic liquids provide tunable partitioning behavior and low miscibility with water.
• Utilized in supported ionic liquid phases (SILPs) for separations and catalytic flow processes.

Catalysis & Reaction Media

• Acts as a non‑volatile, thermally stable solvent for transition‑metal catalysis, including hydrogenation, coupling, and oxidation reactions.
• Supports biphasic catalysis, enabling catalyst recovery and reuse due to phase immiscibility with many organic solvents.
• Provides a controlled ionic environment for organocatalytic and acid‑base‑mediated transformations.

Materials Science & Polymer Engineering

• Used as a structuring agent in polymer electrolytes, ion gels, and composite materials requiring ionic conductivity and mechanical stability.
• Incorporated into nanomaterial synthesis, including templated nanoparticle formation and surface functionalization.
• Serves as a plasticizer or ionic mobility enhancer in specialty polymer matrices.

Spectroscopy, Transport, and Fundamental Studies

• Selected for ionic transport, viscosity, and ion‑pairing studies due to its well‑defined cation structure and hydrophobic PF₆⁻ anion.
• Used in NMR, Raman, and IR investigations of ion dynamics, solvation, and electrochemical interfaces.
• Supports computational benchmarking and experimental validation of ion–solvent interaction models.
