Used in the synthesis of glycopeptide-based vaccines and therapeutic agents, particularly targeting cancer-associated antigens. Its structure mimics tumor-associated carbohydrate antigens, making it valuable in immunological studies and development of anti-cancer vaccines. Commonly employed in solid-phase peptide synthesis to incorporate complex O-linked glycans into peptides, enabling research on glycosylation effects in protein function and cell signaling. Also utilized in creating glycoconjugate libraries for high-throughput screening in drug discovery.
