—— Product Detail ——

- - - - Product Overview
        Benzoin dimethyl ether (Photoinitiator 651, Irgacure 651) is an organic compound with the molecular formula C₁₆H₁₆O₂ and molecular weight of 256.30 g/mol. This white to off-white crystalline solid is a widely used photoinitiator for UV-curable systems. The compound is an α,α-dimethoxyacetophenone derivative that generates free radicals upon UV irradiation.
        Synthetic Process
        
        Synthesis: Benzoin is methylated using dimethyl sulfate or methyl iodide in the presence of a base to form benzoin dimethyl ether
        
        Purification: The crude product is purified by recrystallization from suitable solvents
        
        Drying: The purified product is dried under vacuum
        
        Quality Control: The final product is analyzed to ensure ≥98.0% purity by GC
        
        Mechanism of Action
        
        Norrish Type I Cleavage: Upon UV irradiation, the compound undergoes α-cleavage to generate benzoyl and dimethoxyalkyl radicals
        
        Radical Initiation: The generated radicals initiate the polymerization of acrylate and other vinyl monomers
        
        High Efficiency: Exhibits high photoinitiation efficiency for thick films and pigmented systems
        
        Research Applications & Market Significance
        
        UV Curing: Used in UV-curable coatings, inks, and adhesives
        
        Photoresists: Used in the preparation of photoresists for electronics
        
        3D Printing: Used as a photoinitiator in stereolithography resins
        
        Dental Materials: Used in dental composites and adhesives
        
        Quality Specifications
        
        Purity: ≥98.0% determined by GC
        
        Melting point: 64–67°C
        
        Loss on drying: ≤0.5%
        
        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
