Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and antimicrobial agents. Its structure supports the creation of quinoline-based drugs that target pathogenic organisms. Also employed in research settings to develop novel bioactive molecules due to its reactive halogen groups, which allow for further chemical modifications via cross-coupling reactions. Shows potential in materials science for designing organic semiconductors and fluorescent probes, leveraging its electron-rich aromatic framework.
