N,N'-Dicyclohexylcarbodiimide

N,N'-Dicyclohexylcarbodiimide (DCC, also abbreviated DCCI or DCCD, CAS 538-75-0) is a carbodiimide reagent supplied as a waxy crystalline solid. It carries no assigned E-code. It is classified under HS code 29251900 within the Catalysts and Catalyst Precursors category.

DCC functions as a coupling agent by activating carboxylic acids toward nucleophilic attack, enabling amide and ester bond formation under mild conditions. In pharmaceutical synthesis it drives peptide coupling steps where direct condensation is not feasible. In flavour and fragrance manufacturing it facilitates esterification reactions to produce specific aroma compounds with controlled selectivity.

DCC is available in reagent and technical grades to meet the requirements of pharmaceutical and food-grade production workflows. Suppliers operating under REACH registration can provide material with full SDS documentation and batch-level certificates of analysis. Packaging is typically offered in quantities suited to laboratory through to pilot-scale procurement.
