Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its structure supports the creation of complex heterocyclic systems found in bioactive molecules. Also employed in research settings for designing kinase inhibitors and other enzyme modulators due to its ability to interact with biological targets through π-π stacking and halogen bonding. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving quinoline derivatives.
