Used as a key intermediate in the synthesis of kinase inhibitors, particularly in targeted cancer therapies. Its structure enables selective binding to specific enzyme sites, making it valuable in pharmaceutical research for developing drugs that regulate abnormal cell signaling pathways. Commonly employed in the creation of tyrosine kinase and cyclin-dependent kinase inhibitors, it contributes to the advancement of treatments for tumors and other proliferative diseases. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its functional versatility and stability in various reaction conditions.
