Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in creating complex drug candidates. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build advanced intermediates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its stable aromatic core and reactive halogen site.
