Used as an intermediate in the synthesis of quinolone antibiotics, particularly in the production of fluoroquinolone-class antimicrobial agents. It plays a key role in constructing the core quinoline structure essential for antibacterial activity. Its functional groups allow for selective modifications, enabling the development of compounds with enhanced potency, solubility, and pharmacokinetic properties. Also investigated for its potential in metal chelation and as a building block in medicinal chemistry research targeting enzyme inhibitors.
