Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its nitrile and chloro functional groups allow for selective chemical modifications, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance bioavailability and binding affinity in drug candidates. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
