Used as an intermediate in the synthesis of antimalarial drugs, particularly in the production of chloroquine and related derivatives. It plays a key role in medicinal chemistry for developing compounds that inhibit hemozoin formation in Plasmodium species, thus preventing malaria parasite replication. Also utilized in research for developing new heterocyclic compounds with potential biological activity, including antimicrobial and anticancer agents. Its structure allows functional modifications that enhance drug efficacy and selectivity.
