1-Methyl-1-propylpiperidinium bis(trifluoromethylsulfonyl)imide, CAS: 608140-12-1

Key Applications:

Electrochemical Systems

• Serves as a high‑stability ionic liquid electrolyte component for lithium, sodium, and multivalent metal batteries.
• Enhances electrochemical windows in high‑voltage cells due to the TFSI anion’s oxidative robustness.
• Used in supercapacitor electrolytes where low viscosity and high ionic mobility are required.
• Supports stable SEI formation when blended with lithium salts such as LiTFSI.

Thermal and Chemical Process Media

• Functions as a thermally stable, non‑volatile solvent for high‑temperature synthesis and catalysis.
• Suitable for biphasic reaction systems requiring immiscibility with water and many organics.
• Provides a tunable medium for homogeneous and heterogeneous catalysis, especially in fluorinated environments.

Separation Science

• Applied in liquid–liquid extraction of metal ions, particularly for rare‑earth and transition‑metal separations.
• Used in supported ionic liquid membranes (SILMs) for selective gas permeation, including CO₂ and SO₂ capture.
• Enables extraction processes where hydrophobicity and low coordinating strength are advantageous.

Materials and Polymer Engineering

• Acts as a plasticizer or conductivity enhancer in polymer electrolytes and ion‑conducting films.
• Incorporated into ionogels for flexible electronics, sensors, and solid‑state electrochemical devices.
• Supports dispersion and stabilization of nanoparticles in fluorinated or hydrophobic matrices.

Surface and Interface Engineering

• Used as a surface‑active ionic liquid for modifying electrode interfaces in electrocatalysis.
• Provides stable, low‑volatility lubricating films for tribological applications under extreme conditions.
• Enables anti‑static and charge‑dissipation coatings due to high ionic mobility.

Analytical and Spectroscopic Uses

• Serves as a reference medium for NMR and electrochemical studies requiring low vapor pressure and high purity.
• Used in mass spectrometry ionization studies involving fluorinated anions and non‑coordinating cations.
