Used as a building block in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure supports the development of bioactive molecules due to the quinoline core, which is known for antimicrobial and antimalarial properties. Acts as a ligand in coordination chemistry, forming stable complexes with metal ions, useful in catalysis and material science. Also employed in the synthesis of fluorescent dyes and sensors, leveraging its aromatic and chelating characteristics for detecting metal ions or biological species.
