Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial drugs. Its structure supports the creation of bioactive molecules due to the quinoline core, which is known for its pharmacological activity. It is also employed in research settings for the preparation of novel heterocyclic compounds with potential antimicrobial and anticancer properties. The ester and chloro functional groups allow for further chemical modifications, making it valuable in medicinal chemistry and drug design.
