—— Product Detail ——

- - - - Product Overview
        
        Benzoin (2-hydroxy-1,2-diphenylethanone) is an organic compound with the molecular formula C₁₄H₁₂O₂ and molecular weight of 212.24 g/mol. This white to light yellow crystalline solid is a versatile intermediate in organic synthesis, widely used in pharmaceutical research, photoinitiator formulations, and as a precursor for various functional materials. Benzoin is also the parent compound of the benzoin condensation reaction, a classic carbon-carbon bond-forming reaction.
        
        Synthetic Process
        
        Benzoin is synthesized through various methods:
        
        Benzoin Condensation: Two molecules of benzaldehyde undergo condensation in the presence of a cyanide catalyst (such as sodium cyanide or potassium cyanide) or thiamine (vitamin B1) to form benzoin
        
        Thiamine Catalysis: The greener method using thiamine as a catalyst in ethanol with sodium hydroxide, producing benzoin without using toxic cyanide
        
        Purification: The crude product is purified by recrystallization from ethanol or other suitable solvents
        
        Drying: The purified product is dried under vacuum to yield the final crystalline compound
        
        Mechanism of Action
        
        Benzoin Condensation: A classic cyanide- or thiamine-catalyzed coupling of aromatic aldehydes to form α-hydroxy ketones
        
        Photoinitiation: Benzoin and its derivatives act as Type I photoinitiators, generating free radicals upon UV irradiation
        
        Pharmaceutical Synthesis: Benzoin serves as a key intermediate for the synthesis of various biologically active compounds
        
        Redox Reactions: The α-hydroxy ketone structure enables oxidation to benzil and reduction to hydrobenzoin
        
        Research Applications & Market Significance
        
        Pharmaceutical Research: Intermediate for the synthesis of various drug molecules and biological probes
        
        Photoinitiator: Used in UV-curable coatings, adhesives, and printing inks
        
        Organic Synthesis: Building block for the preparation of chiral ligands, heterocycles, and natural products
        
        Materials Science: Precursor for advanced functional materials
        
        Chemical Education: Classic laboratory demonstration of the benzoin condensation reaction
        
        Quality Specifications
        
        Purity: ≥98.0% (HPLC)
        
        Melting point: 133-137°C
        
        Loss on drying: ≤0.5%
        
        Residue on ignition: ≤0.1%
