Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in the development of anticancer and antimicrobial agents. Derivatives exhibit properties to inhibit certain enzymes, such as tyrosine kinases, which are involved in cancer cell proliferation. Its functional groups enable conjugation in targeted drug delivery systems, enhancing selectivity and efficacy by allowing binding to specific cell surface receptors. Also employed in research for designing fluorescent probes due to the quinoline scaffold’s photophysical properties, useful in cellular imaging and biochemical assays.
