—— Product Detail ——

- - - - Product Overview
        
        2-Bromo-5-methylbenzoic acid is an organic compound with the molecular formula C₈H₇BrO₂ and molecular weight of 215.04 g/mol. This white to off-white crystalline solid is a valuable intermediate in pharmaceutical, agrochemical, and organic synthesis research. The compound features a bromine atom, a methyl group, and a carboxylic acid group on the aromatic ring.
        
        Synthetic Process
        
        Bromination: 5-Methylbenzoic acid is brominated at the 2-position using elemental bromine or NBS in the presence of a catalyst
        
        Oxidation: Alternatively, 2-bromo-5-methylbenzaldehyde is oxidized to the acid
        
        Purification: The crude product is purified by recrystallization from suitable solvents
        
        Drying: The purified product is dried under vacuum
        
        Mechanism of Action
        
        Carboxylic Acid Reactivity: The acid group can be converted to esters, amides, and acid chlorides
        
        Cross-Coupling Substrate: The aryl bromide enables Suzuki-Miyaura and other coupling reactions
        
        Electrophilic Aromatic Substitution: The methyl group directs electrophilic substitution to specific positions
        
        Research Applications & Market Significance
        
        Pharmaceutical Research: Building block for drug discovery programs
        
        Agrochemical Synthesis: Intermediate for herbicides and fungicides
        
        Organic Synthesis: Versatile intermediate for functionalized benzoic acid derivatives
        
        Material Science: Used in the preparation of specialty polymers
        
        Quality Specifications
        
        Purity: ≥98.0% determined by HPLC
        
        Melting point: 138-141°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
