Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial drugs. Its structure supports the formation of quinoline-based active ingredients that exhibit biological activity against pathogens. Commonly employed in research settings for designing new therapeutic agents with antimicrobial and anti-inflammatory properties. Also utilized in the preparation of fluorescent probes due to the inherent photophysical characteristics of the quinoline core, making it valuable in biochemical imaging and diagnostic applications.
