Used in peptide synthesis as a protecting group for amino acids, particularly phenylalanine, to prevent unwanted reactions during the formation of peptide bonds. It helps in the selective deprotection and activation of specific functional groups, ensuring the correct sequence of amino acids in the final peptide product. Commonly employed in the production of pharmaceuticals and bioactive peptides, it plays a crucial role in the development of drugs and therapeutic agents. Additionally, it is utilized in research laboratories for studying protein structures and functions.
