Used as an intermediate in the synthesis of bioactive molecules, particularly in pharmaceuticals and agrochemicals. Exhibits potential in the development of antimicrobial and anti-inflammatory agents due to its reactivity and structural compatibility with heterocyclic compounds. Commonly employed in research settings for constructing fused-ring systems and studying structure-activity relationships in coumarin derivatives. Also utilized in the preparation of fluorescent probes and organic semiconductors owing to its electron-accepting properties and planar aromatic framework.
