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 creating complex molecules for drug discovery. Commonly employed in cross-coupling reactions such as Suzuki or Negishi couplings to build advanced organic frameworks. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its halogenated pyridine core, which enhances bioavailability and target binding.
