Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its halogenated structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex quinoline-based molecules. Also employed in research to design compounds with antimicrobial and anti-inflammatory activity. Its aromatic and electron-deficient core supports use in materials science, especially in the development of organic semiconductors and ligands for catalysis.
