1,1'-Carbonyldiimidazole; CDI Appearance:White to off white crystalline powder Melting point :116~122℃ Assay ≥98% N,N'-Carbonyldiimidazole is a white crystals with a melting point of 116 C. It is hydrolyzed by water quickly. It is used as a coupling agent for the synthesis of peptides. When reacted with amino acids or peptide esters, it releases the imidazole group to couple the peptides. N,N'-Carbonyldiimidazole (CDI) is also a very reactive reagent in organic synthesis, mainly in converting alcohols and amines into esters, amides, ketones, and ureas. The reactivity is similar to acid chlorides for the activation of acids as imidazolides reagent. CDI undergoes reaction with peroxide to form the peroxycarboxylic acid and imidazole group can be reduced to form aldehydes from the carboxylic acid. CDI reagent is also used to make beta-keto sulfones, sulfoxides and beta-enamino acid derivatives. CDI is a carbonyl-transfer reagent for the synthesis of various heterocycles. N,N'-Carbonyldiimidazole (CDI) is also Lisinopril Intermediates. For more info please visit http://www.nbinno.com/en/products/fine_chemicals/Otherchemicals/CDI.html
