        1,1'-Carbonyldiimidazole Chemical Properties,Uses,Production

        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

        1,1'-Carbonyldiimidazole is a peptide coupling reagent,it is used 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.]
