Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting protein kinases involved in inflammatory diseases and cancer. Its structure supports high selectivity and binding affinity to specific enzyme active sites, making it valuable in developing targeted therapies. Also investigated for use in central nervous system drug candidates due to its ability to cross the blood-brain barrier. Commonly employed in structure-activity relationship (SAR) studies to optimize potency and metabolic stability in preclinical compounds.
