Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex quinoline-based molecules. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to form carbon-carbon bonds in drug discovery programs. Also utilized in the preparation of kinase inhibitors and antimicrobial compounds due to its ability to interact with biological targets.
