Used in the synthesis of pharmaceutical intermediates, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its heterocyclic structure, which can enhance binding affinity to biological targets. Also employed in research settings for the design of novel bioactive compounds, including antiviral and anti-inflammatory agents. Its chlorinated aromatic system allows for further functionalization through cross-coupling reactions, making it valuable in drug discovery and development.
