Used as a key intermediate in the synthesis of sialic acid derivatives, particularly in the development of neuraminidase inhibitors. Plays an important role in glycosylation reactions for constructing complex oligosaccharides found on cell surfaces. Commonly applied in pharmaceutical research for designing antiviral agents, especially against influenza viruses. Its adamantane moiety enhances stability and binding affinity, making it valuable in drug design targeting viral entry and infection mechanisms. Also utilized in biochemical tools for studying sialyltransferase and neuraminidase enzyme activities.
