Used as a key intermediate in the synthesis of complex organic molecules, particularly in pharmaceutical and medicinal chemistry. Its primary application lies in peptide synthesis and the development of macrocyclic compounds, where the Boc-protected amine groups allow for selective deprotection and stepwise construction of nitrogen-containing rings. It is also employed in the preparation of chelating agents and ligands for metal ions, useful in catalysis and imaging agents. Due to its well-defined spacing of nitrogen atoms, it supports the design of molecular scaffolds in drug discovery and supramolecular chemistry.
