For professionals engaged in complex chemical synthesis, sourcing high-quality reagents is not just a matter of convenience, but a fundamental requirement for successful outcomes. N,N'-Carbonyldiimidazole (CDI), bearing the CAS number 530-62-1, is one such critical compound, widely used as an activating and coupling agent in organic synthesis, particularly in peptide chemistry. As a buyer, understanding what constitutes quality CDI and where to procure it reliably is paramount. This guide focuses on the key aspects of purchasing CDI, emphasizing the value proposition offered by reputable manufacturers and suppliers.

Understanding the Criticality of Purity and Assay

The efficacy of CDI in reactions like peptide synthesis, esterification, and carbamate formation is directly linked to its purity. Impurities can lead to side reactions, reduced yields, and complicated purification processes. Therefore, when you buy N,N'-Carbonyldiimidazole, always look for detailed specifications. A high assay, typically ≥98.0% as stated by manufacturers, is a strong indicator of quality. This high purity ensures that the CDI will react as expected, facilitating predictable and efficient synthesis. Reliable suppliers, such as ourselves, provide comprehensive documentation, including certificates of analysis (COAs), which detail the assay and other critical parameters.

Key Applications Driving Demand

The demand for CDI is driven by its indispensable role in several high-value fields:

  • Peptide Synthesis: Facilitates the formation of amide bonds, crucial for creating therapeutic peptides.
  • Organic Synthesis: Acts as a versatile reagent for ester, carbamate, and anhydride formation.
  • Pharmaceutical Intermediates: Serves as a key building block or activating agent in drug synthesis pathways.
  • Biochemical Research: Used in the synthesis of nucleoside triphosphates and other biomolecules.

For those seeking a dependable peptide synthesis reagent manufacturer or a supplier of pharmaceutical intermediates, understanding these applications helps in defining procurement needs.

The Advantage of Sourcing from a Dedicated Manufacturer

Procuring CDI from a direct manufacturer offers significant advantages. Firstly, it ensures the best possible N,N'-Carbonyldiimidazole price, especially for bulk quantities, as it cuts out intermediary markups.
