Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective modification at multiple sites, making it valuable in medicinal chemistry for optimizing drug potency and selectivity. Commonly employed in the preparation of compounds targeting tyrosine kinases and other ATP-binding site enzymes involved in signal transduction pathways. Also utilized in research settings to develop novel pharmaceuticals with improved metabolic stability and bioavailability.
