Used in organic synthesis as a key intermediate for the development of pharmaceuticals, particularly in the creation of quinoline-based compounds. It plays a role in the synthesis of potential drug candidates for treating diseases like malaria, cancer, and bacterial infections. Its bromo and ester functional groups make it versatile for further chemical modifications, enabling the production of complex molecules with therapeutic properties. Additionally, it is utilized in research to study the biological activity of quinoline derivatives and their mechanisms of action.
