Used as a key intermediate in the synthesis of selective kinase inhibitors, particularly in pharmaceutical research targeting inflammatory diseases and certain cancers. Its structure enables strong binding to specific enzyme active sites, making it valuable in developing drugs that modulate cell signaling pathways. Commonly employed in the preparation of small-molecule therapeutics with high potency and selectivity. Also utilized in structure-activity relationship (SAR) studies to optimize drug candidates for improved metabolic stability and bioavailability.
