Used in the synthesis of pharmaceutical intermediates, particularly in the development of antimalarial and anticancer agents. Its structure serves as a key building block in heterocyclic chemistry, enabling the construction of complex quinoline-based molecules. Commonly employed in research settings for designing bioactive compounds due to its amine and ester functional groups, which allow for further chemical modifications. Also utilized in fluorescent probe development, taking advantage of the quinoline core’s inherent photophysical properties.
