Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its protected diamine structure allows for selective functionalization in multi-step organic syntheses. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems due to the stability and ease of removal of the tert-butoxycarbonyl (Boc) protecting groups. Also utilized in the preparation of advanced intermediates for drug discovery programs targeting cancer and inflammatory diseases.
