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 constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions to introduce the quinoline scaffold into target molecules. Also utilized in the preparation of kinase inhibitors and antimicrobial compounds due to its ability to interact with biological targets through hydrogen bonding and π-π stacking interactions.
