Used primarily in organic synthesis, this compound serves as a key intermediate in the production of pharmaceuticals, particularly in the development of antimalarial and antimicrobial agents. Its structure is valuable in creating quinoline derivatives, which are explored for their potential therapeutic properties. Additionally, it finds application in the synthesis of dyes and agrochemicals due to its reactive chloroquinoline backbone. Researchers also utilize it in the study of chemical reactions and mechanisms involving halogenated heterocycles.
