Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. Its structure enables selective binding to enzyme active sites, making it valuable in developing drugs that modulate cell signaling pathways. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance potency and selectivity in drug candidates. Also utilized in the preparation of small molecule inhibitors targeting tyrosine kinases and other ATP-binding proteins.
