Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial drugs. It serves as a building block in medicinal chemistry due to its quinoline scaffold, which is known for biological activity. Also employed in research for developing compounds with antimicrobial and anticancer properties. Its derivatives are explored for kinase inhibition in targeted cancer therapies. Additionally, it finds use in the preparation of fluorescent probes and dyes due to its optical properties.
