Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of bioactive molecules due to the presence of both iodine and quinoline moieties. The iodine atom allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, enabling the construction of complex molecular structures. Commonly employed in the development of medicinal compounds, particularly in research targeting kinase inhibitors and antimicrobial agents. Also utilized in materials science for the synthesis of ligands in catalytic systems.
