Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and fine chemicals. Its structure supports the creation of complex quinoline-based compounds, which are often found in bioactive molecules. Commonly applied in research settings for drug discovery, especially in pathways requiring substituted quinolines. Also utilized in the preparation of fluorescent dyes and sensors due to its electron-rich aromatic system. Shows potential in medicinal chemistry for designing compounds with antimicrobial or anticancer activity.
