—— Product Detail ——

- - - - Product Overview
        
        4-tert-Butylbenzaldehyde is an aromatic aldehyde with the molecular formula C₁₁H₁₄O and molecular weight of 162.23 g/mol. This colorless to light yellow liquid is a valuable intermediate in organic synthesis, widely used in the preparation of pharmaceuticals, fragrances, and specialty chemicals. The tert-butyl group provides steric bulk that influences the reactivity and selectivity of the aldehyde group.
        
        Synthetic Process
        
        4-tert-Butylbenzaldehyde is synthesized through various methods:
        
        Friedel-Crafts Acylation: tert-Butylbenzene undergoes formylation using dichloromethyl methyl ether (Cl₂CHOMe) or chloroform in the presence of aluminum chloride (Gattermann-Koch reaction) to introduce the aldehyde group at the para position
        
        Oxidation: 4-tert-Butyltoluene can be oxidized to the corresponding aldehyde using selective oxidation methods
        
        Purification: The crude product is purified by fractional distillation under reduced pressure
        
        Quality Control: The final product is analyzed to ensure ≥98.0% purity
        
        Mechanism of Action
        
        Electrophilic Aromatic Substitution: The tert-butyl group directs electrophilic substitution to the para position
        
        Aldehyde Reactivity: The aldehyde group participates in condensation, reduction, and oxidation reactions
        
        Steric Effects: The bulky tert-butyl group provides steric hindrance that can influence reaction selectivity
        
        Research Applications & Market Significance
        
        Pharmaceutical Research: Building block for various drug compounds
        
        Fragrance Industry: Intermediate for the synthesis of musk fragrances and other aroma compounds
        
        Agrochemical Synthesis: Intermediate for herbicide and pesticide production
        
        Organic Synthesis: Versatile building block for functionalized aromatic compounds
        
        Material Science: Used in the preparation of specialty polymers
        
        Quality Specifications
        
        Purity: ≥98.0% (GC)
        
        Boiling point: 128-130°C (20 mmHg)
        
        Density: 0.970 g/mL at 20°C
        
        Refractive index: n²⁰/D 1.529
        
        Flash point: >110°C
        
        Storage: 2-8°C, sealed, under inert atmosphere
        
        Stable for 24 months when properly stored
        
        Packaging & Shipping
        
        Research quantities: 25g, 100g amber glass bottles
        
        Bulk quantities: 500g, 1kg amber glass bottles
