Used primarily in peptide synthesis as a protecting group for β-glutamic acid. It helps in preventing unwanted reactions at the β-glutamic acid site during the formation of peptide bonds. The Boc group protects the amino group, while the OBzl group protects the side-chain carboxyl group, allowing selective deprotection and coupling in multi-step peptide synthesis. This compound is particularly useful in the synthesis of complex peptides and proteins, where precise control over the addition of amino acids is required. It is also employed in the development of pharmaceuticals, especially in the production of peptide-based drugs, where maintaining the integrity of specific amino acids is crucial for the drug's activity and stability.
