1-Hexylimidazole, CAS: 33529-01-0

Key Applications:

1. Ionic Liquid and Electrolyte Precursor

• Serves as a key intermediate for synthesizing imidazolium‑based ionic liquids with tailored hydrophobicity and viscosity.
• Used in the preparation of room‑temperature ionic liquids for electrochemical devices, including supercapacitors and advanced battery electrolytes.
• Supports formulation of ionic liquid additives that enhance ionic conductivity and thermal stability.

2. Phase‑Transfer and Organocatalysis

• Functions as a nucleophilic catalyst or ligand in alkylation, acylation, and condensation reactions.
• Employed as a phase‑transfer catalyst in biphasic systems where increased alkyl chain length improves organic solubility.
• Useful in catalytic systems requiring mild basicity and tunable steric/electronic properties.

3. Surfactant, Solubilizer, and Interface Modifier

• The C6 alkyl chain provides amphiphilic character, enabling use as a co‑surfactant or solubilizing agent in organic‑rich formulations.
• Applied in dispersions, emulsions, and nanomaterial stabilization where imidazole headgroups promote surface coordination.

4. Coordination Chemistry and Metal‑Binding Applications

• Acts as a neutral ligand for transition‑metal complexes, supporting catalytic studies, homogeneous catalysis, and materials synthesis.
• Used in preparing metal–organic frameworks (MOFs) and coordination polymers where alkyl‑substituted imidazoles tune pore environment and hydrophobicity.

5. Polymer and Material Modification

• Incorporated as a functional monomer or chain‑end modifier in specialty polymers to introduce ionic, basic, or coordination‑active sites.
• Utilized in surface treatments and coatings where imidazole groups enhance adhesion, corrosion resistance, or metal‑ion interaction.

6. Synthetic Intermediate

• Serves as a building block for quaternization to form 1‑hexyl‑3‑substituted imidazolium salts.
• Used in the synthesis of surfactants, ionic liquid monomers, and functionalized heterocycles.
