Application

CDI (1,1′-Carbonyldiimidazole) can be used:
  • In the activation of malonic acid derivatives to prepare carbonyl imidazoles by mild decarboxylation.
  • In the activation of cellulose membranes for the development of immunosensors.
  • In the synthesis of substituted 1,3-oxazolo[4,5-d] pyridazinones.
  • As a reagent for the conversion of various hydroxamic acids to isocyanates by Lossen rearrangement.
  • In the synthesis of 1,3,4-oxadiazole derivatives , and peptide thioesters in water.
  • As an acylation agent for the synthesis of carbamates.

General description

CDI serves as a powerful coupling reagent in peptide synthesis and organic chemistry.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. 1,1′-carbonyldiimidazole (CDI) is an alternative to highly toxic insidious poison phosgene and thus aligns with the principle "Designing Safer Chemicals".
