Used as a key intermediate in the synthesis of pharmaceuticals, particularly in antimalarial drugs. It serves as a building block in the development of quinoline-based compounds that exhibit antimicrobial and anticancer activities. Its structure allows for easy modification, making it valuable in medicinal chemistry for drug design and optimization. Also employed in research for developing new bioactive molecules and in the preparation of fluorescent probes for biological imaging due to the inherent fluorescence of the quinoline scaffold.
