Used as a key intermediate in the synthesis of quinolone antibiotics, particularly in the production of fluoroquinolone-class antimicrobial agents. Its structure allows for functionalization that enhances the pharmacokinetic properties of the final drug compounds, including improved solubility and bacterial targeting. Commonly employed in pharmaceutical research and development for optimizing antibiotic efficacy against resistant bacterial strains. Also utilized in the preparation of biologically active molecules in medicinal chemistry due to its amine and carboxylic acid functional groups, which facilitate coupling reactions and molecular diversification.
