1-Heptyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, CAS: 425382-14-5

Key Applications:

1. High‑Temperature Electrolytes

• Stable ionic conductivity across wide thermal windows
• Suitable for lithium, sodium, and multivalent battery research
• Compatible with high‑voltage cathode materials due to the NTf₂⁻ anion’s oxidative stability
• Useful in supercapacitor electrolyte formulations where low volatility is essential

2. Solvent for Catalysis and Organic Synthesis

• Hydrophobic ionic liquid ideal for biphasic catalysis, especially transition‑metal systems
• Enhances selectivity and turnover in hydrogenation, alkylation, and coupling reactions
• Recyclable solvent phase for green chemistry workflows

3. Extraction and Separation Processes

• Effective for liquid–liquid extraction of aromatic hydrocarbons, metal ions, and biomolecules
• Hydrophobicity enables water‑immiscible extraction systems
• Useful in CO₂ capture studies when paired with functional additives

4. Materials Science and Surface Engineering

• Employed as a templating agent for nanoporous materials
• Used in thin‑film deposition, including IL‑assisted CVD and electrodeposition
• Enhances dispersion of nanoparticles, graphene, and carbon nanotubes

5. Electrochemical Devices and Interfaces

• Forms stable electric double layers for interfacial studies
• Suitable for ionic‑liquid gating in advanced electronic materials
• Used in corrosion inhibition research due to strong surface adsorption

6. Tribology and Lubrication

• Low vapor pressure and high thermal stability support high‑temperature lubricant applications
• Reduces friction and wear in metal–metal and metal–ceramic contacts
• Compatible with additive packages for extreme‑pressure lubrication

7. Biotechnology and Analytical Chemistry

• Medium for enzyme stabilization in non‑aqueous catalysis
• Enhances chromatographic separations (IL‑modified stationary phases)
• Used in mass spectrometry ionization studies due to low volatility
