Used in the synthesis of glycoconjugate vaccines and immunological research, this compound serves as a building block for constructing complex carbohydrate-peptide structures. Its protected sugar moieties allow for precise assembly of oligosaccharide chains found in bacterial or tumor-associated antigens. The Fmoc group enables solid-phase peptide synthesis, making it suitable for automated platforms. Researchers use it to study immune responses by presenting tumor or pathogen-like sugar epitopes on peptide scaffolds, aiding in the development of synthetic vaccines and diagnostic tools.
