Application

5-Bromo-2,3-difluorobenzonitrile serves as a versatile building block in Suzuki-Miyaura and Buchwald-Hartwig couplings for constructing polyfluorinated biaryl systems in drug discovery. Its electron-deficient aromatic ring enhances reactivity in nucleophilic aromatic substitutions (SNAr) for agrochemical and pharmaceutical intermediates. The compound is also employed in liquid crystal and OLED material synthesis, where the bromo-cyano motif facilitates π-conjugation tuning.
