Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, particularly in the production of third-generation quinolones with enhanced antimicrobial activity. Its structure supports the development of agents effective against both Gram-negative and Gram-positive bacteria. Commonly employed in pharmaceutical research to build the quinoline core found in drugs targeting DNA gyrase and topoisomerase IV. Also utilized in the development of novel derivatives for potential antiviral and anticancer applications due to its favorable reactivity and substitution pattern.
