This compound is widely used in peptide synthesis as a protecting group for the amino acid tryptophan. It helps to prevent unwanted reactions during the formation of peptide bonds, ensuring the correct sequence and structure of the peptide. The Boc (tert-butoxycarbonyl) group provides stability under various reaction conditions, while the N-hydroxysuccinimide ester facilitates efficient coupling with other amino acids or peptides. It is particularly valuable in solid-phase peptide synthesis, where precise control over the assembly of peptide chains is essential. Additionally, it is utilized in the preparation of modified peptides for research in biochemistry, pharmaceuticals, and drug development.
