Boc-Orn-OH is widely used in peptide synthesis as a protected form of ornithine. It serves as a key building block in the creation of complex peptides, ensuring the ornithine residue remains stable during the synthesis process. This compound is particularly valuable in medicinal chemistry for developing peptide-based drugs, where precise control over amino acid sequences is crucial. Additionally, it finds applications in biochemical research for studying protein interactions and enzyme mechanisms, providing a reliable tool for modifying peptide structures. Its protective Boc group can be easily removed under mild acidic conditions, making it a versatile choice for various synthetic pathways.
