Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and antimicrobial agents. Its quinoline backbone provides a key structural motif known for biological activity. Commonly employed in research settings to design kinase inhibitors and other bioactive molecules. Also utilized in the preparation of fluorescent probes due to its favorable photophysical properties. Serves as a building block in medicinal chemistry for structure-activity relationship studies targeting central nervous system disorders.
