Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting tyrosine kinases involved in cancer cell proliferation. Its structure supports binding to ATP sites in enzymes, making it valuable in developing anticancer agents. Also explored in the design of anti-inflammatory and neuroprotective compounds due to its ability to cross the blood-brain barrier. Commonly employed in structure-activity relationship (SAR) studies to optimize drug candidates for improved potency and selectivity.
