Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure allows for further functionalization, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Commonly employed in cross-coupling reactions such as Suzuki and Buchwald-Hartwig to introduce quinoline-based scaffolds into bioactive molecules. Also utilized in the preparation of kinase inhibitors and antimicrobial agents.
