Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding to enzyme active sites, enhancing drug efficacy. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles. Also utilized in research settings for creating analogs in structure-activity relationship (SAR) studies. The trifluoroacetate salt form improves solubility and stability during synthetic processes.
