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 creating analogs with potential antitumor, antiviral, or anti-inflammatory properties. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to build complex heterocyclic systems. Also utilized in agrochemical research for designing new active ingredients in crop protection agents.
