General description

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.

Application

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

N-Acylimidazoles were recognized in the early 1950s as reactive intermediates suitable for the acylation of amino compounds. The search for better coupling reagents than DCC led to the development of CDI (1,1’-carbonyldiimidazole) and related carbonylimidazoles.

Amide bonds are ubiquitous in both nature and industrial applications. They are vital to the structure and function of biological macromolecules and polymers. The importance of this functionality has resulted in numerous approaches to its formation, ranging from stoichiometric activation of carboxylic acids to more recent advances in catalytic amide bond formation.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
