Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules. Its structure supports the introduction of tert-butyl carbamate-protected amine groups, enabling controlled amine reactivity in multi-step organic reactions. Commonly applied in medicinal chemistry for constructing cyclopropane-containing analogs, which can enhance metabolic stability and binding affinity in drug candidates. Also utilized in the preparation of protease inhibitors and receptor modulators due to the steric and electronic properties imparted by the dimethylphenyl and cyclopropyl groups.
