1-Methyl-1-propylpyrrolidinium tetrafluoroborate, CAS: 327022-59-3

Key Applications:

Electrochemical Systems

• Employed as a non‑volatile electrolyte or electrolyte additive in supercapacitors, lithium‑free metal batteries, and hybrid ion devices.
• Supports wide electrochemical windows, enabling high‑voltage cell designs and improved cycling stability.
• Used in electrodeposition studies for metals and semiconductors where moisture‑sensitive, inert media are required.

Catalysis & Organic Synthesis

• Serves as a tunable reaction medium for transition‑metal catalysis, C–C coupling, oxidation, and hydrogenation reactions.
• Enhances selectivity and yield in ionic‑liquid‑assisted synthesis due to its thermal stability and low coordinating character.
• Utilized in biphasic catalytic systems to improve catalyst recovery and recyclability.

Separation Science & Extraction

• Applied in liquid–liquid extraction of metal ions, dyes, and organic compounds, leveraging its hydrophobicity and adjustable solvation behavior.
• Used in supported ionic liquid membranes (SILMs) for gas separation, CO₂ capture, and pervaporation processes.

Materials Science & Nanotechnology

• Acts as a templating or stabilizing medium for nanoparticle synthesis, enabling controlled morphology and dispersion.
• Incorporated into polymer electrolytes and ionogels to enhance ionic transport and mechanical stability.
• Used in surface modification and thin‑film fabrication where ionic‑liquid‑based processing improves uniformity and adhesion.

Thermal & Chemical Stability Applications

• Suitable for high‑temperature reaction environments due to its low vapor pressure and resistance to decomposition.
• Utilized in studies of ionic‑liquid structure–property relationships, solvation dynamics, and ion transport mechanisms.
