Used extensively in peptide synthesis as a protecting group for the amine functionality of alanine. It helps prevent unwanted side reactions during the formation of peptide bonds. The group is stable under the conditions of peptide coupling but can be selectively removed using mild base treatment, making it highly valuable in the production of complex peptides and proteins. It is particularly useful in solid-phase peptide synthesis, where sequential addition of amino acids is required. Additionally, it finds application in the synthesis of peptide-based pharmaceuticals and research peptides, ensuring high purity and yield of the final product.
