Industrial Applications of 2-Ethylimidazole (CAS 1072-62-4)

2-Ethylimidazole (2-EIM, CAS 1072-62-4) is a substituted imidazole derivative with the molecular formula C₅H₈N₂. As a class, imidazole compounds have been used in thermoset polymer chemistry and specialty organic synthesis for several decades. Nexal Inc. supplies ≥98.5% GC grade material, with domestic distribution across North America and export support to Latin American markets.

• Thermoset Polymer Chemistry

Imidazole derivatives are a long-established class of nitrogen-donor compounds used in epoxy and related thermoset systems. 2-Ethylimidazole offers good solubility behavior in common epoxy resin chemistries and a favorable handling profile relative to lower-melting imidazole homologs.

End-Use Categories: Industrial protective coatings, structural adhesive chemistries, printed circuit board base materials, general electrical insulation resins

• Polyurethane Chemistry

Nitrogen-based heterocycles such as 2-ethylimidazole are studied as components in certain polyurethane catalyst systems, including formulations developed as alternatives to organotin chemistries. Selection of catalyst loading and co-catalyst combinations remains the responsibility of the formulator.

End-Use Categories: General foam systems, elastomeric formulations, industrial sealants and coatings

• Specialty Organic Synthesis

With a free N-H site and a 2-ethyl substituent on the imidazole ring, 2-EIM is used as a building block in specialty organic synthesis where an imidazole nucleus is required. Documented academic use areas include ionic liquid precursor chemistry and metal coordination chemistry.

End-Use Categories: Imidazolium-based ionic liquid intermediates, ligand chemistry, custom organic synthesis

Physical Form: Supplied as white to light-yellow flakes / crystalline powder, melting point 83–87 °C, in standard 25 kg fiber drums. Handling: store tightly closed in cool, dry conditions. Refer to the SDS for full safety and handling information.
