2-Methyl-1-propylpyridinium bis(trifluoromethylsulfonyl)imide, CAS: 1456877-99-8

Key Applications:

Electrochemical Systems

• High‑stability electrolyte component for lithium, sodium, and multivalent metal batteries, leveraging the TFSI⁻ anion’s wide electrochemical window.
• Ionic‑liquid medium for supercapacitors requiring low volatility and strong thermal resilience.
• Conductive additive in redox‑flow batteries to enhance ion mobility and suppress side reactions.

Thermal & Chemical Stability Applications

• Heat‑transfer and thermal‑management fluids in high‑temperature or vacuum environments, where non‑flammability and low vapor pressure are essential.
• Replacement for volatile organic solvents in high‑temperature synthesis, catalytic cycles, and controlled‑atmosphere reactions.

Catalysis & Organic Synthesis

• Reaction medium for transition‑metal catalysis, including C–C and C–N bond‑forming reactions that benefit from ionic‑liquid stabilization.
• Solvent for selective extraction, biphasic catalysis, and phase‑transfer processes, especially where hydrophobicity and chemical inertness are required.

Separation Science & Extraction

• Hydrophobic ionic liquid for liquid–liquid extraction of metal ions, hydrophobic organics, and fluorinated species.
• Tunable medium for chromatographic method development, particularly in ion‑pairing or non‑aqueous separations.

Materials Science & Polymer Engineering

• Additive for ion‑conducting polymers, gels, and elastomers to improve conductivity, flexibility, and thermal stability.
• Processing aid in membrane fabrication, enabling controlled microstructure and enhanced transport properties.

Surface Science & Nanotechnology

• Stabilizing medium for nanoparticle synthesis, preventing aggregation and enabling narrow size distributions.
• Ionic‑liquid phase for surface modification, thin‑film deposition, and interfacial engineering.

Tribology & Lubrication

• High‑performance lubricant or lubricant additive for extreme‑pressure and high‑temperature environments, benefiting from TFSI⁻‑based ionic liquids’ low wear and friction coefficients.
