1-Phenylimidazole, CAS: 7164-98-9

Key Applications:

Organic Synthesis and Catalysis

• Functions as a heterocyclic building block in the preparation of pharmaceuticals, agrochemicals, and specialty intermediates.
• Serves as a ligand or nucleophilic catalyst in acylation, alkylation, and condensation reactions.
• Used in N‑functionalization and C–N bond‑forming transformations for constructing complex heteroaromatic scaffolds.

Polymer and Materials Chemistry

• Incorporated into imidazole‑functional polymers to enhance thermal stability, mechanical strength, and chemical resistance.
• Acts as a curing accelerator or crosslinking component in epoxy and polyurethane systems.
• Supports development of high‑performance coatings, adhesives, and resins requiring elevated heat resistance.

Coordination and Organometallic Chemistry

• Employed as a neutral N‑donor ligand for transition‑metal complexes used in catalysis, sensing, and redox‑active materials.
• Enables tuning of electronic and steric properties in metal–ligand frameworks.

Analytical and Research Applications

• Used as a reference heterocycle in mechanistic studies of proton transfer, aromaticity, and tautomerism.
• Serves as a probe molecule in spectroscopic investigations, including NMR, IR, and UV–vis studies of heteroaromatic interactions.

Specialty and Emerging Uses

• Explored in ionic liquid precursor synthesis, particularly for designing aromatic imidazolium salts with tailored solvation or electrochemical properties.
• Utilized in functional surface modification, where aromatic imidazoles improve adhesion or introduce reactive sites.
