Used as a key intermediate in the synthesis of pharmaceuticals, particularly in antimalarial drugs. Its structure supports the development of compounds with biological activity against resistant strains of malaria. Also employed in the preparation of kinase inhibitors for cancer therapy. Serves as a building block in medicinal chemistry for designing new bioactive molecules due to its ability to form stable derivatives. Applied in research settings for developing fluorescent probes and sensors owing to the quinoline core’s photophysical properties.
