Description and Uses
2-Methylimidazole is used as a raw material for the preparation of nitroimidazole antibiotics, which is useful in combat anaerobic bacterial and parasitic infections. It acts as a ligand in coordination chemistry. It is also employed as a hardener or accelerator for epoxy resin and auxiliary agent for textile dyes. Further, it acts as a catalyst for refolding of enhanced colored fluorescent protein. It is also useful as a building block in the synthesis of biologically active compounds. In addition to this, it is used as an active pharmaceutical ingredient intermediate such as metronidazole and dimetridazole.
