Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for building quinoline-based bioactive molecules. Also employed in the preparation of fluorescent dyes and optoelectronic materials due to its conjugated aromatic system. Commonly utilized in research settings for constructing complex heterocyclic compounds through cross-coupling reactions.
