2-bromo-1-chloro-3,5-difluorobenzene; CAS No.: 1020198-58-6;2-bromo-1-chloro-3,5-difluorobenzene. PROPERTIES: 2-bromo-1-chloro-3,5-difluorobenzene is a multiply halogenated aromatic compound with molecular formula C6HBrClF2. It typically exists as a colorless liquid with a mild aromatic odor, having a boiling point around 115-120 C. The compound has limited water solubility but dissolves well in organic solvents like dichloromethane or diethyl ether. It exhibits moderate thermal stability but may decompose when exposed to high temperatures or strong bases, releasing toxic halogen-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 molecules. The bromo substituent enables cross-coupling reactions to form biaryl structures, while the chloro and fluoro groups provide additional sites for functionalization (The Journal of Organic Chemistry). In pharmaceutical development, 2-bromo-1-chloro-3,5-difluorobenzene contributes to the synthesis of antimicrobial and anticancer agents where the halogenated aromatic scaffold enhances binding to biological targets (European Journal of Medicinal Chemistry). The compound also finds application in materials science as a building block for organic electronics, where its electron-deficient aromatic core influences the electronic properties of derived materials (Advanced Functional Materials).
