Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antimalarial and antimicrobial agents. Its structure supports the formation of complex heterocyclic systems that exhibit biological activity against resistant strains of pathogens. Commonly employed in research settings for constructing novel drug candidates due to its reactive functional groups, which allow for selective modifications. Also utilized in the preparation of fluorescent probes and dyes, where its nitrile and hydroxy groups enhance photostability and emission properties.
