Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in creating biologically active compounds. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build complex heterocyclic systems found in drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its halogenated pyridine core, which enhances binding affinity and metabolic stability.
