This chemical is widely used in peptide synthesis as a protecting group for amino acids. It helps in the selective protection of the threonine residue during the formation of peptide bonds, ensuring that the amino group remains intact while other reactions take place. This is particularly useful in solid-phase peptide synthesis, where sequential addition of amino acids is required. Additionally, it aids in preventing unwanted side reactions and improves the overall yield and purity of the synthesized peptides. Its application is crucial in the production of complex peptides and proteins for research, pharmaceuticals, and biotechnology.
