Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports selective binding to protein targets involved in cell signaling pathways. Commonly employed in research settings to design drugs targeting tyrosine kinases due to the presence of trifluoromethyl and aminoaryl groups that enhance biological activity and metabolic stability. Also utilized in medicinal chemistry for optimizing lead compounds through modification of amine functionalities protected by the tert-butoxycarbonyl (Boc) group.
