Used in glycoscience research for studying sialyltransferase and glycosidase enzyme specificity due to its selectively protected sialic acid and galactose moieties. The compound serves as a synthetic intermediate in the preparation of complex glycoconjugates, particularly in the development of neoglycoproteins and glycoarrays for probing biological recognition events. The methyl and benzyl/benzoyl protecting groups allow for stepwise deprotection and coupling in solid-phase oligosaccharide synthesis. Its modified sialic acid structure helps mimic natural sialylated glycans involved in cell signaling and pathogen attachment, making it valuable in designing inhibitors for viral adhesion or inflammation-related processes.
