Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its halogenated quinoline structure allows for selective cross-coupling reactions, enabling the introduction of functional groups in complex molecule assembly. Commonly employed in research settings for designing kinase inhibitors and antimicrobial agents due to its ability to interact with biological targets involving enzyme inhibition. Also utilized in agrochemical research for developing novel pesticides with improved efficacy and selectivity.
