2,5-dichloro-4-fluorobenzotrifluoride; CAS No.: 89634-77-5;2,5-dichloro-4-fluorobenzotrifluoride. PROPERTIES: 2,5-dichloro-4-fluorobenzotrifluoride is a chlorinated and fluorinated aromatic compound with molecular formula C7H3Cl2F4. It typically exists as a colorless liquid with a boiling point around 125-130 C. The compound has limited water solubility but dissolves well in organic solvents like chloroform or carbon tetrachloride. It exhibits moderate thermal stability but may decompose when exposed to high temperatures or strong bases, releasing toxic chlorine and fluorine-containing fumes. Proper storage involves keeping it in tightly sealed containers below 25 C, away from heat sources and incompatible materials. APPLICATIONS: In organic synthesis, this compound serves as a versatile intermediate for creating complex aromatic systems. The dichloro and fluoro substituents provide multiple sites for cross-coupling and nucleophilic substitution reactions (Tetrahedron Letters). In pharmaceutical development, 2,5-dichloro-4-fluorobenzotrifluoride contributes to the synthesis of antimicrobial agents where the halogenated aromatic scaffold enhances binding to microbial targets (Antimicrobial Agents and Chemotherapy). The compound also finds application in materials science as a building block for organic electronics, where its electron-deficient aromatic core modulates the electronic properties of derived materials (Journal of Materials Chemistry C).
