Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its structure allows for selective derivatization, making it valuable in medicinal chemistry for building complex heterocyclic systems. It is also employed in the preparation of fluorescent probes due to the quinoline core, which exhibits inherent photophysical properties useful in bioimaging and sensor technologies. Additionally, it serves as a building block in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
