Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure supports the creation of complex heterocyclic compounds that interact with biological targets. Also employed in research for developing new quinoline-based drugs due to its electron-rich aromatic system and ability to form stable derivatives. Shows potential in materials science for designing organic semiconductors and fluorescent probes because of its rigid planar framework and favorable photophysical properties.
