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 allows selective binding to enzyme active sites, making it valuable in developing drugs that modulate cellular signaling pathways. Also employed in the optimization of central nervous system agents due to its ability to cross the blood-brain barrier. Commonly utilized in structure-activity relationship (SAR) studies to enhance potency and selectivity of drug candidates.
