Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules targeting central nervous system disorders and metabolic diseases. Its protected amine functionality allows for selective reactions in multi-step organic syntheses, making it valuable in constructing complex drug architectures. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the rigid cyclobutyl scaffold, which can enhance potency and metabolic stability. Also utilized in the preparation of kinase inhibitors and receptor modulators where steric and conformational control are critical.
