—— Product Detail ——

- - - - Product Overview
        
        4-Bromo-2-fluorophenylboronic acid is an organic compound with the molecular formula C₆H₅BBrFO₂ and molecular weight of 218.82 g/mol. This white to off-white crystalline solid is a valuable intermediate in pharmaceutical, agrochemical, and material science research. The compound features a boronic acid group, a bromine atom, and a fluorine atom on the aromatic ring.
        
        Synthetic Process
        
        Borylation: 1-Bromo-2-fluoro-4-iodobenzene is converted to the boronic acid via halogen-metal exchange followed by reaction with a trialkyl borate
        
        Purification: The crude product is purified by recrystallization from suitable solvents
        
        Drying: The purified product is dried under vacuum
        
        Mechanism of Action
        
        Suzuki-Miyaura Coupling: The boronic acid group enables Suzuki-Miyaura cross-coupling reactions with aryl halides
        
        Cross-Coupling Substrate: The aryl bromide can also participate in coupling reactions
        
        Fluorinated Building Block: The fluorine atom provides unique electronic properties and metabolic stability
        
        Research Applications & Market Significance
        
        Pharmaceutical Research: Building block for drug discovery programs
        
        Agrochemical Synthesis: Intermediate for herbicides and fungicides
        
        Material Science: Used in the preparation of functional materials and liquid crystals
        
        Organic Synthesis: Versatile intermediate for functionalized aromatic compounds
        
        Quality Specifications
        
        Purity: ≥98.0% determined by HPLC
        
        Melting point: 178-182°C
        
        Loss on drying: ≤0.5%
        
        Storage: 2-8°C, sealed, protected from light
        
        Stable for 24 months when properly stored
