Sigma-Aldrich N N-Carbonyldiimidazol

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. 1,1′-carbonyldiimidazole (CDI) is an alternative to highly toxic insidious poison phosgene and thus aligns with the principle "Designing Safer Chemicals". For more information see the article Controlled Synthesis of Asymmetric Dialkyl and Cyclic Carbonates Using the Highly Selective Reactions of Imidazole Carboxylic Esters.

Coupling agent in the synthesis of dipolar polyamides for nonlinear optical applications[1] and polypeptides.[2] Also used to make β-keto sulfones and sulfoxides,[3] lead sequestering agents,[4] and β-enamino acid derivatives.[5]
