—— Product Detail ——

- - - - Product Overview
        4,4‘-Bipyridine is an organic compound with the molecular formula C₁₀H₈N₂ and molecular weight of 156.19 g/mol. This white to off-white crystalline solid is a valuable bidentate ligand in coordination chemistry and a key building block for metal-organic frameworks (MOFs) and supramolecular assemblies. The compound features two pyridine rings connected at the 4-positions.
        Synthetic Process
        
        Coupling: 4-Bromopyridine is coupled using palladium-catalyzed or nickel-catalyzed methods
        
        Purification: The crude product is purified by recrystallization or sublimation
        
        Drying: The purified product is dried under vacuum
        
        Quality Control: The final product is analyzed to ensure ≥98.0% purity by HPLC
        
        Mechanism of Action
        
        Bidentate Coordination: The two nitrogen atoms coordinate to metal centers, forming bridging or chelating complexes
        
        MOF Construction: Acts as a linear linker in the synthesis of metal-organic frameworks
        
        Electron Transport: The conjugated bipyridine system facilitates electron transport in functional materials
        
        Research Applications & Market Significance
        
        Coordination Chemistry: Classic ligand for the preparation of metal complexes and coordination polymers
        
        MOF Synthesis: Key linker for the construction of porous metal-organic frameworks
        
        Material Science: Used in the preparation of electrochromic materials and molecular wires
        
        Supramolecular Chemistry: Used in the assembly of host-guest systems and molecular machines
        
        Quality Specifications
        
        Purity: ≥98.0% determined by HPLC
        
        Melting point: 111–114°C
        
        Loss on drying: ≤0.5%
        
        Storage: 2-8°C, sealed, protected from light
        
        Stable for 36 months when properly stored
        
        Packaging & Shipping
        
        Research quantities: 5g, 25g amber glass vials
        
        Bulk quantities: 100g, 500g amber glass bottles
        
        Shipped at ambient temperature
