Application
4-Bromo-2-fluoroaniline (CAS 367-24-8) is a halogenated aniline building block widely used in pharmaceutical, agrochemical, and material science research. In drug discovery, it serves as a key pharmaceutical intermediate for the synthesis of 4-anilinoquinazoline derivatives, which are potent anticancer agents that selectively inhibit EGFR and VEGFR tyrosine kinases involved in cancer cell growth and angiogenesis. It has also been employed as a precursor in the synthesis of monoacylglycerol acyltransferase 2 (MGAT2) inhibitors for antidiabetic research to reduce triglyceride levels. In agrochemical development, the fluorine and bromine substituents contribute to the stability and efficacy of herbicides and crop protection products. In materials science, this compound enables diazotization and coupling reactions to produce biaryl dyes, pigments, and functional polymers. As a versatile organic building block, it participates in palladium-catalyzed cross-coupling reactions (Suzuki, Buchwald-Hartwig) and nucleophilic aromatic substitution (SNAr). It is also used as an analytical reference standard in chromatography for pharmaceutical quality control and impurity profiling.
