Used as an intermediate in the synthesis of quinolone antibiotics, particularly in the production of fluoroquinolone drugs which exhibit broad-spectrum antibacterial activity. It plays a key role in constructing the core quinoline scaffold essential for antimicrobial efficacy. Also employed in research for developing novel bioactive molecules with potential antiviral and anticancer properties. Its functional groups allow for easy modification, making it valuable in medicinal chemistry for structure-activity relationship studies.
