Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, particularly in the production of advanced antimicrobial agents. Its structure supports the development of drugs with enhanced activity against resistant bacterial strains. Commonly employed in pharmaceutical research to modify quinolone cores for improved pharmacokinetics and broader spectrum efficacy. Also utilized in the development of metal-organic frameworks (MOFs) due to its chelating properties, enabling applications in catalysis and sensing. Investigated for use in medicinal chemistry for targeted drug delivery systems owing to its ability to coordinate with metal ions and bind biological targets.
