Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, particularly in the production of advanced antimicrobial agents. Its structure supports high antibacterial activity against both Gram-positive and Gram-negative bacteria. Commonly employed in pharmaceutical research and development to create derivatives with improved potency, pharmacokinetics, and reduced resistance. Also utilized in the preparation of drugs targeting respiratory, urinary tract, and skin infections due to its strong DNA gyrase and topoisomerase IV inhibition properties.
