2,5-difluoro-4-(trifluoromethyl)benzonitrile; CAS No.: 261945-24-8;2,5-difluoro-4-(trifluoromethyl)benzonitrile. PROPERTIES: 2,5-difluoro-4-(trifluoromethyl)benzonitrile is a fluorinated and trifluoromethylated aromatic nitrile with molecular formula C8H3F5N. It typically exists as a colorless liquid with a boiling point around 130-135 C. The compound has limited water solubility but dissolves well in organic solvents like dichloromethane or THF. It exhibits moderate thermal stability but may decompose when exposed to high temperatures or strong acids, releasing toxic nitrogen-containing fumes. Proper storage involves keeping it in tightly sealed containers below 20 C, protected from light and moisture. APPLICATIONS: In organic synthesis, this compound serves as a valuable intermediate for developing agrochemicals. The difluoro and trifluoromethyl substitution provides strong electron-withdrawing effects that enhance herbicidal activity, while the nitrile group offers sites for further functionalization (Pest Management Science). In materials science, 2,5-difluoro-4-(trifluoromethyl)benzonitrile contributes to the creation of functional organic materials with tailored electronic properties. Its fluorinated aromatic core and nitrile group influence the electronic characteristics of derived materials, useful in optoelectronic applications such as organic light-emitting diodes (Chemistry of Materials). The nitrile group can be further transformed through hydrolysis or reduction to form amides or amines, expanding its utility in multistep syntheses (The Journal of Organic Chemistry).
