Used in peptide synthesis as a protecting group for glutamine, ensuring selective reactions during the formation of peptide bonds. It helps prevent unwanted side reactions and maintains the integrity of the glutamine residue. Commonly employed in solid-phase peptide synthesis (SPPS) for the production of peptides and proteins in pharmaceutical research. Its stability under various reaction conditions makes it a reliable choice for complex peptide assembly. Additionally, it is utilized in the development of bioactive peptides and therapeutic agents, contributing to advancements in drug discovery and biotechnology.
