Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of fluorinated aromatic drugs where selective functionalization is required. Its protected carboxylic acid group and free amino group allow for sequential coupling reactions, making it valuable in constructing complex molecules for medicinal chemistry. Commonly employed in the preparation of kinase inhibitors and other bioactive agents where fluorine substitution enhances metabolic stability and binding affinity. The tert-butyl ester group facilitates solubility in organic solvents and simplifies purification during multi-step syntheses.
