N,N’-Carbonyldiimidazole (CDI) is a versatile organic reagent primarily employed as a coupling agent in peptide synthesis and for preparing carboxylic acid derivatives. It serves as a safe substitute for phosgene, facilitating the synthesis of amides, esters, and acid anhydrides. A key advantage is its reaction efficiency, generating only imidazole as a benign, gaseous byproduct, which simplifies purification. This makes CDI exceptionally valuable in pharmaceutical and polymer chemistry.

N,N’-Carbonyldiimidazole (CDI), with the CAS number 530-62-1, is a highly versatile organic reagent widely recognized as a safe and efficient coupling agent. It is primarily used in peptide synthesis and for the preparation of various carboxylic acid derivatives, such as amides, esters, and acid anhydrides, serving as a crucial substitute for highly toxic phosgene. A significant operational advantage of CDI is its reaction mechanism, which generates only imidazole as a byproduct. This byproduct is a relatively benign gas that is easily removed, thereby greatly simplifying the purification process and minimizing waste. This characteristic, combined with its high reactivity, makes CDI exceptionally valuable across multiple industries, most notably in pharmaceutical manufacturing for drug development and in polymer chemistry. The chemical appears as a white crystalline powder with a molecular formula of C7H6N4O and a molecular weight of 162.15. It has a melting point of 117-122°C and a boiling point of approximately 288.8°C, with a density of 1.303 g/cm³.
As a reliable N,N’-Carbonyldiimidazole manufacturer, we offer a comprehensive supply solution tailored to global client needs. We provide high-purity CDI (99% to 99.5%) and support flexible order quantities, including free samples ranging from 10 to 1000 grams (with the customer bearing the freight, which is refundable upon bulk order). We ensure prompt and adaptable logistics, using couriers like DHL for small packages (3-7 days) and air or sea freight for larger quantities (1-40 days). Our payment options are equally versatile, accepting T/T, L/C, PayPal for smaller values, and even Bitcoin. We are experienced in exporting to markets like the United States and the UK and maintain a 95.8% positive review rate. All shipments are accompanied by complete documentation, including a Commercial Invoice, Packing List, Bill of Lading, Certificate of Analysis (COA), and other required certificates to ensure smooth customs clearance and compliance with your market regulations.
