Description
1-Methylimidazole (CAS 616-47-7) is a nitrogen-containing heterocyclic compound supplied under trade names including LUPRAGEN NMI, Araldite DY 070, and DY 070. It carries no assigned E-code and is classified under HS code 29332990. The compound is commercially available as a liquid with the molecular formula C4H6N2.
In epoxy resin systems, 1-methylimidazole acts as a latent curing catalyst, accelerating ring-opening polymerisation at controlled temperatures to produce thermoset coatings and structural adhesives. In pharmaceutical synthesis, it functions as a buffering agent, stabilising reaction pH within defined ranges to protect sensitive intermediates. Both roles depend on its nucleophilic nitrogen centre driving the underlying chemistry.
The compound is supplied in technical and high-purity grades compliant with REACH registration requirements. Standard packaging includes drums and IBCs suited to industrial procurement volumes. Buyers should confirm grade specification against application requirements, particularly where pharmaceutical or electronic-grade purity thresholds apply.
