—— Product Detail ——

- - - - Product Overview
        
        4,4'-Biphenyldicarboxaldehyde is an organic compound with the molecular formula C₁₄H₁₀O₂ and molecular weight of 210.23 g/mol. This white to off-white crystalline solid is a valuable intermediate in material science, pharmaceutical, and organic synthesis research. The compound features two aldehyde groups at the 4,4'-positions of a biphenyl system.
        
        Synthetic Process
        
        Formylation: Biphenyl is diformylated using the Vilsmeier-Haack reaction or other formylation methods
        
        Oxidation: Alternatively, 4,4'-bis(hydroxymethyl)biphenyl is oxidized to the dialdehyde
        
        Purification: The crude product is purified by recrystallization from suitable solvents
        
        Drying: The purified product is dried under vacuum
        
        Mechanism of Action
        
        Aldehyde Reactivity: The aldehyde groups participate in condensation, reduction, and oxidation reactions
        
        Schiff Base Formation: Reacts with amines to form Schiff base ligands
        
        MOF Construction: Used as a linker in the synthesis of metal-organic frameworks (MOFs)
        
        Cross-Coupling: Can be further functionalized through the aldehyde groups
        
        Research Applications & Market Significance
        
        Material Science: Key building block for MOFs, covalent organic frameworks (COFs), and functional polymers
        
        Pharmaceutical Research: Building block for drug discovery programs
        
        Organic Synthesis: Versatile intermediate for functionalized biphenyl derivatives
        
        Supramolecular Chemistry: Used in the construction of host-guest systems
        
        Quality Specifications
        
        Purity: ≥98.0% determined by HPLC
        
        Melting point: 110-113°C
        
        Loss on drying: ≤0.5%
        
        Residue on ignition: ≤0.1%
        
        Storage: 2-8°C, sealed, protected from light
        
        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
