This compound is primarily utilized in the field of peptide synthesis, where it serves as a protected derivative of L-ornithine, specifically N^α-(benzyloxycarbonyl)-N^δ-(tert-butoxycarbonyl)-L-ornithine. Its structure includes orthogonal protective groups (Cbz on the α-amino and Boc on the side-chain amino) that safeguard these functionalities during the synthesis process, preventing unwanted side reactions. The free carboxylic acid allows for direct activation and peptide coupling. This makes it particularly valuable in the stepwise construction of complex peptides containing ornithine residues, ensuring high purity and yield. Additionally, it is employed in the development of peptide-based drugs and bioactive molecules, where precise control over the sequence and structure of amino acids is crucial. Its stability under various reaction conditions makes it a reliable choice for researchers in organic and medicinal chemistry.
