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 explored in the design of central nervous system agents due to its ability to cross the blood-brain barrier. Employed in structure-activity relationship (SAR) studies to optimize potency and metabolic stability in drug candidates.
