—— Product Detail ——

- - - - Product Overview
        
        N,N'-Dicyclohexylcarbodiimide (DCC) is an organic compound with the molecular formula C₁₃H₂₂N₂ and molecular weight of 206.33 g/mol. This white to off-white crystalline solid is one of the most widely used coupling reagents in organic synthesis, particularly in peptide synthesis for amide bond formation. DCC is valued for its high efficiency, ease of use, and availability.
        
        Synthetic Process
        
        Synthesis: Dicyclohexylcarbodiimide is prepared by the reaction of dicyclohexylamine with phosgene or via thiourea oxidation methods
        
        Purification: The crude product is purified by distillation or crystallization
        
        Quality Control: Purity is verified by GC or titration analysis
        
        Mechanism of Action
        
        Amide Coupling: DCC activates carboxylic acids to form reactive O-acylisourea intermediates that are readily attacked by amines to form amide bonds
        
        Peptide Synthesis: The reagent enables efficient peptide bond formation under mild conditions
        
        Other Applications: Used for esterification, lactonization, and other condensation reactions
        
        Research Applications & Market Significance
        
        Peptide Synthesis: Key reagent for solid-phase and solution-phase peptide synthesis
        
        Pharmaceutical Research: Used in drug discovery for amide bond formation
        
        Polymer Chemistry: Applied in polymer modification and functionalization
        
        Natural Product Synthesis: Essential reagent in total synthesis
        
        Quality Specifications
        
        Purity: ≥99.0% (GC)
        
        Melting point: 34-36°C
        
        Boiling point: 122-124°C (6 mmHg)
        
        Storage: 2-8°C, sealed, dry
        
        Stable for 24 months when properly stored
        
        Packaging & Shipping
        
        Research quantities: 25g, 100g amber glass bottles
        
        Bulk quantities: 500g, 1kg amber glass bottles
        
        Shipped at ambient temperature
