General description

1-Methylimidazole is an N-donor ligand generally used in the preparation of coordinate complexes.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product has been enhanced for catalysis. Find details here.

Application

1-Methylimidazole may be used as a starting material to synthesize:
  • 1-(2-hydroxypropyl)-3-methylimidazolium salts used as ionic liquids
  • 1,3-dimethylimidazoyl-2-ylidene borane, a stable and easy to handle N-heterocyclic carbene borane
  • It can act both as a catalyst and a solvent in the synthesis of aldononitrile acetates from aldoses.
