Used in peptide synthesis as a protecting group for threonine, ensuring selective reactions during the formation of peptide bonds. It helps prevent unwanted side reactions and allows for the controlled assembly of complex peptides. Commonly employed in the production of pharmaceuticals, particularly in the development of peptide-based drugs. Its stability under various reaction conditions makes it a valuable tool in organic and medicinal chemistry research. Additionally, it aids in the study of protein structure and function by enabling the synthesis of specific peptide sequences.
