1,1'-Carbonyldiimidazole Usage And Synthesis


Chemical Properties White crystalline powder


Uses Used in the synthesis of peptides. Contains up to 10% imidazole.


Uses peptide coupling reagent


Uses CDI is mainly employed to convert alcohols and amines into carbamates, esters, and ureas. It is also used in the synthesis of peptides and nucleoside triphosphates.


Uses In the synthesis of peptides. Reacts readily with carboxylic acids to form acyl imidazoles; subsequent reaction with amines to form amides goes smoothly.


Purification Methods Crystallise it from *benzene or tetrahydrofuran in a dry-box and store it dry. [Hearn Methods Enzymol 135 102 1987, Beilstein 23/4 V 245.]
