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 medicinal chemistry for constructing complex molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build advanced drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its heterocyclic framework. Its bromine moiety facilitates easy modification, enabling rapid exploration of structure-activity relationships in drug discovery programs.
