Z-Chg-OH is widely used in peptide synthesis as a protecting group for the carboxyl function of amino acids. It helps in preventing unwanted side reactions during the formation of peptide bonds. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it ensures the selective deprotection and coupling of amino acids, leading to the efficient production of complex peptides. Additionally, Z-Chg-OH is employed in the synthesis of bioactive peptides and pharmaceuticals, where precise control over the sequence and structure of the peptide chain is crucial. Its stability under various reaction conditions makes it a reliable choice for researchers and industrial applications in peptide chemistry.
