Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form stable heterocyclic structures that interact with biological targets. Also employed in the preparation of agrochemicals and functional materials where nitrogen-rich aromatic systems enhance performance. Its chloro group allows for easy functionalization via cross-coupling reactions, making it valuable in drug discovery and materials science.
