2-Methylimidazole

2-Methylimidazole (CAS 693-98-1) is a nitrogen-containing heterocyclic compound supplied as a crystalline powder, commonly identified by the abbreviations 2MZ or 2MI and sold under trade names including Curezol 2MZ and Denka CN 25. It carries no assigned E-code and is also referenced as NSC 21394 in chemical databases.

In epoxy resin systems, 2-Methylimidazole acts as a latent curing agent and accelerator, initiating ring-opening polymerisation of epoxide groups to form cross-linked thermoset networks used in printed circuit boards and structural adhesives. It also functions as a pH buffer and catalyst in polyurethane and coating formulations, where controlled basicity drives reaction kinetics at defined temperatures.

This material is available in technical and high-purity grades and is subject to REACH registration requirements within the EU. It is classified under HS code 29332990 for import and export purposes. Packaging formats typically include fibre drums and multi-layer bags suited to industrial procurement volumes.
