Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors and anticancer agents. Its structure allows for selective functionalization, making it valuable in the development of targeted therapies. Commonly employed in cross-coupling reactions such as Suzuki or Sonogashira to build complex heterocyclic systems. Also explored in agrochemical research for designing novel pesticides due to its halogenated heteroaromatic framework.
