Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in antimalarial drugs. Its structure supports the development of bioactive molecules due to the quinoline moiety, which is known for antiparasitic and antimicrobial activity. Also employed in the preparation of dyes and fluorescent probes for biochemical labeling, thanks to its electron-donating properties and ability to form stable conjugates. Shows potential in materials science for organic semiconductors owing to its aromatic and electron-transport characteristics.
