Used in peptide synthesis as a protecting group for ornithine, facilitating the creation of specific peptide sequences. It is particularly valuable in research settings where controlled and selective reactions are required. The benzyl ester group enhances solubility and stability during reactions, making it easier to handle in complex synthetic processes. Additionally, it plays a role in studying enzyme mechanisms and interactions involving ornithine. Its application extends to the development of pharmaceuticals and bioactive peptides, where precise molecular construction is critical.
