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 ATP pockets in kinase enzymes, making it valuable in developing targeted therapies. Also investigated for use in central nervous system drugs due to its ability to cross the blood-brain barrier. Commonly employed in structure-activity relationship (SAR) studies to optimize potency and selectivity in drug candidates.
