Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial drugs. Its structure supports the creation of compounds with biological activity against Plasmodium species. Also employed in research for agrochemicals, contributing to the design of plant growth regulators and crop protection agents. Shows utility in organic synthesis for building complex heterocyclic systems due to its reactive halogen sites and aromatic core. Limited solubility in water but dissolves well in organic solvents, making it suitable for use in solvent-based reactions. Investigated for potential applications in materials science, especially in the development of fluorescent dyes and sensors owing to the quinoline backbone’s photophysical properties.
