Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows selective modification to target specific signaling pathways involved in tumor growth. Commonly employed in medicinal chemistry for optimizing potency and selectivity in drug candidates. Also utilized in the preparation of small molecule inhibitors targeting tyrosine kinases and other ATP-binding site enzymes. Its halogen groups enable further functionalization through cross-coupling reactions, making it valuable in combinatorial chemistry and pharmaceutical research.
