Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial drugs. It serves as a building block for quinoline-based compounds that exhibit biological activity against Plasmodium species. Also employed in agrochemicals for the formulation of crop protection agents due to its ability to enhance the efficacy of certain pesticides. Its carboxylic acid group allows for easy derivatization, making it valuable in medicinal chemistry for creating libraries of bioactive molecules.
