Used as an intermediate in the synthesis of complex carbohydrates and glycosyl donors, particularly in the preparation of oligosaccharides and glycoconjugates for pharmaceutical research. Its bromine functionality allows for selective coupling reactions, making it valuable in constructing glycosidic bonds with stereochemical control. Commonly employed in the development of antiviral and antibacterial agents, vaccines, and diagnostic probes where precise sugar moieties are required. Also utilized in chemoenzymatic synthesis and solid-phase oligosaccharide assembly due to its reactivity and stability under various protecting group strategies.
