Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in creating complex heterocyclic systems found in drug candidates. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build carbon-carbon and carbon-nitrogen bonds. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its electron-deficient pyridine core. Its nitrile and bromo groups offer dual reactivity sites, enabling sequential transformations in multi-step syntheses.
