1-Methyl-3-pentylimidazolium hexafluorophosphate, CAS: 280779-52-4

Key Applications

Catalysis and Reaction Media

• Serves as a non‑volatile solvent for transition‑metal catalysis, enabling improved selectivity and recyclability of catalytic systems.
• Supports biphasic and multiphasic reaction designs where hydrophobic ionic liquids enhance product separation.
• Provides a stable medium for organometallic transformations sensitive to moisture or conventional organic solvents.

Electrochemical Systems

• Functions as an electrolyte component in electrochemical cells requiring wide electrochemical windows and low vapor pressure.
• Useful in studies of ion transport, electrode interfaces, and ionic‑liquid‑based capacitors.
• Supports development of ionic‑liquid‑modified electrodes for sensing and analytical applications.

Extraction and Separation

• Enables liquid–liquid extraction of metal ions, organic compounds, and hydrophobic analytes due to its immiscibility with water and tunable solvation behavior.
• Applied in separation workflows for aromatic compounds, dyes, and environmental contaminants.
• Suitable for designing task‑specific extraction systems where PF₆⁻ anions contribute to phase stability.

Materials Science and Polymer Processing

• Acts as a structuring agent or plasticizer in polymer synthesis and processing, influencing conductivity, morphology, and mechanical properties.
• Supports fabrication of ion‑conductive films, membranes, and composite materials.
• Useful in templating studies for nanoporous materials and ionic‑liquid‑assisted self‑assembly.

Spectroscopy and Fundamental Studies

• Provides a controlled, low‑volatility environment for NMR, IR, and UV‑Vis investigations of solvation, ion pairing, and molecular dynamics.
• Used in benchmarking studies comparing alkyl‑chain effects across imidazolium PF₆ ionic liquids.
• Supports mechanistic research on ion–solvent interactions and phase behavior.
