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 exhibit biological activity. Commonly employed in research settings to build quinoline-based drug candidates. Also utilized in the preparation of fluorescent dyes and sensors due to its ability to participate in coordination with metal ions. Plays a role in the development of organic semiconductors and optoelectronic materials.
