Used as a key intermediate in the synthesis of biologically active quinoline derivatives, particularly in pharmaceutical research targeting anticancer and antimicrobial agents. Its furan and benzylamino functional groups enable molecular diversification for structure-activity relationship studies. Commonly employed in medicinal chemistry for developing kinase inhibitors and fluorescent probes due to its conjugated aromatic system. Also applied in the preparation of organic semiconductors and optoelectronic materials because of its electron-transporting properties.
