1-Hexyl-2-methylimidazole, CAS: 82410-68-2

Key Applications:

1. Precursor and Intermediate in Ionic Liquid Synthesis

• Serves as an alkylated imidazole building block for preparing hydrophobic ionic liquids with long‑chain cations.
• Useful for generating salts with bis(trifluoromethylsulfonyl)imide (TFSI), PF₆⁻, BF₄⁻, and other anions for electrochemical and materials applications.
• Enables tuning of viscosity, polarity, and thermal stability in task‑specific ionic liquids.

2. Corrosion Inhibition and Surface Protection

• Long alkyl chain improves adsorption on metal surfaces, making it a candidate for corrosion‑inhibitor formulations in acidic or chloride‑rich environments.
• Can be blended with other heterocyclic inhibitors to enhance film‑forming behavior.

3. Phase‑Transfer and Catalytic Applications

• Acts as a nucleophilic base or ligand in organic synthesis, particularly in alkylation, substitution, and condensation reactions.
• The hydrophobic C6 chain improves compatibility with nonpolar media, enabling biphasic or solvent‑free catalytic systems.

4. Surfactant and Amphiphilic Additive

• Amphiphilic structure supports micelle formation and interfacial modification.
• Can be incorporated into formulations requiring controlled wetting, dispersion, or stabilization.

5. Electrolyte and Additive in Energy‑Related Systems

• Serves as a precursor for cationic species used in electrolytes for batteries, supercapacitors, and electrochemical devices.
• The imidazole core contributes to ionic conductivity, while the hexyl chain enhances hydrophobicity and thermal robustness.

6. Polymer and Material Modification

• Functions as a reactive monomer or chain‑transfer component in specialty polymer systems.
• Can be grafted onto polymer backbones to introduce ionic or amphiphilic character, improving adhesion, flexibility, or chemical resistance.

7. Coordination and Organometallic Chemistry

• Nitrogen donor site enables coordination to transition metals, supporting catalyst development or mechanistic studies.
• Useful in designing metal–organic frameworks (MOFs) or functionalized ligands with tailored solubility.
