Primarily used in peptide synthesis as a protecting group for histidine. It helps prevent unwanted side reactions during the formation of peptide bonds. The Boc group protects the amino group, while the Z group protects the imidazole side chain of histidine, ensuring selective reactions. This compound is particularly valuable in the production of complex peptides and proteins, where precise control over the sequence and structure is crucial. It is also employed in pharmaceutical research for developing peptide-based drugs and bioactive molecules. Its stability and ease of removal under specific conditions make it a preferred choice in solid-phase peptide synthesis.
