Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective modification to target specific signaling pathways involved in tumor growth. Commonly employed in medicinal chemistry for constructing potent, selective inhibitors of tyrosine kinases and other ATP-binding site-containing enzymes. Also utilized in the preparation of small-molecule therapeutics for inflammatory diseases and viral infections due to its favorable binding properties and scaffold versatility.
