Used as an 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 molecules for drug discovery. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build advanced intermediates in agrochemicals and medicinal chemistry. Also utilized in the preparation of functional materials where aromatic heterocycles are needed for electronic or optical properties.
