Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly antibiotics such as fluoroquinolones. Its structure supports the formation of core scaffolds in antimicrobial agents, enhancing activity against gram-negative and gram-positive bacteria. Also employed in the development of antiviral and anticancer compounds due to its ability to interact with biological targets like DNA gyrase and topoisomerase IV. Additionally, it serves as a building block in heterocyclic chemistry for creating novel bioactive molecules in medicinal research.
