Used as a key intermediate in the synthesis of quinolone-based antibacterial agents. Its structure supports the development of fluoroquinolone antibiotics, which are effective against a broad spectrum of bacteria. The compound's pyridyl and carboxylic acid groups enable molecular modifications that enhance antimicrobial activity, bioavailability, and target binding to bacterial DNA gyrase and topoisomerase IV. It is primarily employed in pharmaceutical research and development for creating novel anti-infective drugs.
