Used as a key intermediate in the synthesis of quinolone-class antibiotics, particularly in the production of fluoroquinolone antimicrobial agents. Its structure enables functionalization at multiple sites, making it valuable for developing compounds with activity against Gram-positive and Gram-negative bacteria. It is also employed in medicinal chemistry research for designing novel heterocyclic compounds with potential anticancer, antiviral, and anti-inflammatory properties. Additionally, it serves as a building block in the preparation of kinase inhibitors and other biologically active molecules in pharmaceutical development.
