N,N'- Carbonyl diimidazole

N,N'-Carbonyldiimidazole (CDI) is an organic compound. It is a white, crystalline solid that acts as a potent coupling reagent in peptide and nucleic acid synthesis. CDI facilitates the formation of amide bonds between carboxylic acids and amines, making it valuable in the production of peptides, proteins, and other complex molecules. It is also used in various organic synthesis applications due to its reactivity and efficiency. CDI reacts with water and alcohols, so it should be handled under anhydrous conditions and stored in a dry environment to maintain its effectiveness and prevent decomposition.
