Used as a key intermediate in the synthesis of complex carbohydrates and glycosylated natural products. Its protected hydroxyl groups allow selective deprotection and glycosylation reactions, making it valuable in the preparation of oligosaccharides and glycoconjugates for pharmaceutical research. Commonly employed in the development of antiviral and anticancer agents where precise sugar moieties are required. The ethynyl group enables further functionalization via click chemistry, facilitating bioconjugation and labeling in biochemical probes.
