Used as a protected diamine building block in organic synthesis, particularly in pharmaceutical and agrochemical industries. The Boc-protected amine group allows selective reaction at the other amine site, enabling stepwise construction of complex molecules. Commonly employed in peptide synthesis and the preparation of nitrogen-containing heterocycles. Its stability under various reaction conditions makes it suitable for multi-step synthetic routes where controlled deprotection is required. Also utilized in the development of functionalized polymers and as an intermediate in the synthesis of bioactive compounds.
