Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the creation of compounds with high selectivity toward specific signaling pathways involved in tumor growth. Also employed in research for designing antimicrobial and anti-inflammatory agents due to its electron-rich aromatic core and reactive chlorine site, which allows for further functionalization. Commonly utilized in medicinal chemistry for scaffold modification and structure-activity relationship (SAR) studies.
