Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex quinoline-based molecules. It is also employed in research settings to develop novel bioactive compounds with potential anticancer and anti-inflammatory properties. Due to the presence of multiple halogen atoms, it serves as a versatile building block in cross-coupling reactions such as Suzuki and Buchwald-Hartwig aminations.
