Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to the presence of both amine and trifluoromethyl functional groups, which enhance binding affinity and metabolic stability in drug molecules. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) requiring selective aromatic substitution patterns. Its tert-butyl carbamate (Boc) protection allows for controlled deprotection during multi-step syntheses, making it valuable in solid-phase and solution-phase peptide-like assembly processes.
