Product Details

1-Methylimidazole CAS#616-47-7

1-Methylimidazole or N-methylimidazole is an aromatic heterocyclic organic compound with the formula CH3C3H3N2. It is a colorless to yellow liquid, with an amine-like odor. It is miscible with water. N-methylimidazole is an important raw material for the synthesis of pharmaceutical intermediates, used in the preparation of losartan, nizofenone, 1-Methyl-1H-imidazole-5-carbonyl chloride hydrochloride and naphazoline hydrochloride, etc. It is also used as a specialty solvent, a base, and as a precursor to some ionic liquids.

Product Application of 1-Methylimidazole CAS#616-47-7

1-Methylimidazole is an aprotic solvent. It is a derivative of imidazole used in the production of pharmaceuticals, pesticides, ion exchange resins, dye intermediates, textile auxiliaries, photographic chemicals, and corrosion inhibitors. It can also be used as a catalyst for the manufacture of polyurethane and a curing agent for epoxy resins. For example, when 1-methylimidazole is added to an aqueous diethylenetriamine (DETA) solution, high CO2 loading can be achieved through phase separation of the absorbent during CO2 absorption[1].
