Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Its structure supports the development of bioactive molecules, particularly in the construction of nitrogen-containing heterocyclic compounds. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to form carbon-carbon bonds in the synthesis of complex quinoline derivatives. Also explored in medicinal chemistry for potential antimicrobial and anticancer agents due to the biological activity associated with iodinated quinolines.
