Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and antibacterial agents. Its structure supports the formation of quinoline-based compounds that exhibit biological activity against resistant strains of pathogens. Also employed in research for designing novel kinase inhibitors and anti-inflammatory drugs due to its ability to interact with specific enzyme targets. Its carboxylic acid group allows for easy derivatization, making it valuable in medicinal chemistry for creating compound libraries.
