Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure supports the formation of complex heterocyclic systems that exhibit biological activity against specific enzymes and pathogens. Commonly employed in medicinal chemistry for constructing kinase inhibitors and antimicrobial compounds due to its reactive functional groups, which allow for selective derivatization. Also utilized in research settings to develop fluorescent probes and sensors owing to its electron-withdrawing nitrile and chloro groups that enhance photostability and signal response.
