Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports binding to enzyme active sites, making it valuable in designing drugs that target specific signaling pathways in tumor cells. Also employed in research for central nervous system therapies due to its ability to cross the blood-brain barrier. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
