Used in peptide synthesis as a protecting group for tryptophan, ensuring selective reactions during the formation of peptide bonds. Its Boc groups shield the amino and indole functionalities, preventing unwanted side reactions. Commonly employed in solid-phase peptide synthesis (SPPS) to create complex peptides with high precision. Also serves as an intermediate in the production of pharmaceuticals and bioactive peptides, particularly those requiring tryptophan residues. Its stability under acidic conditions makes it suitable for deprotection steps in peptide synthesis workflows.
