Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antipsychotic drugs. It serves as a building block in medicinal chemistry due to its quinoline scaffold, which is known for biological activity. Also employed in the preparation of agrochemicals and functional materials where nitrogen-containing heterocycles enhance performance. Its chloro group allows for further functionalization through cross-coupling reactions, making it valuable in research and development of bioactive molecules.
