Used in peptide synthesis, particularly for protecting histidine residues during the formation of complex peptides. It helps prevent unwanted side reactions by shielding reactive sites, ensuring the correct sequence and structure of the peptide. Commonly employed in the production of pharmaceuticals, such as peptide-based drugs, where precise molecular assembly is critical. Its protective groups are selectively removed after synthesis, allowing for the final functional peptide to be obtained. Also utilized in research for developing bioactive peptides and studying their interactions with biological targets.
