Application
1-Fluoro-2-iodobenzene (CAS 348-52-7) is a valuable ortho-substituted aryl halide widely used as a versatile building block in medicinal chemistry and organic synthesis. The iodine atom enables efficient palladium-catalyzed cross-coupling reactions including Suzuki-Miyaura, Buchwald-Hartwig, Sonogashira, and Heck couplings, while the fluorine provides metabolic stability and modulates electronic properties. This compound serves as a key pharmaceutical intermediate for the synthesis of bioactive molecules such as kinase inhibitors, antiviral agents, and anti-inflammatory drugs. In agrochemical research, it is a precursor for modern herbicides and fungicides. Its unique ortho-fluoroiodo substitution pattern allows regioselective functionalization and rapid diversification of heterocyclic scaffolds. Additionally, it is employed in materials science for the preparation of organic semiconductors and liquid crystal displays. High-purity 1-fluoro-2-iodobenzene ensures reproducible results in high-throughput screening, SAR studies, and GMP manufacturing.
