Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective modification in drug design, especially in targeting tyrosine kinases involved in cell signaling pathways. Commonly employed in medicinal chemistry for constructing potent and selective inhibitors in treatments for lung, breast, and other solid tumors. Also utilized in research settings to explore structure-activity relationships (SAR) in pyrrolopyridine-based compounds.
