[(2R,3R,4S,5R,6R)-6-bromo-3,4,5-tris(2,2-dimethylpropanoyloxy)oxan-2-yl]methyl 2,2-dimethylpropanoate

This compound is a protected glycosyl bromide, specifically a per-O-pivaloylated alpha-D-glucopyranosyl bromide. It is primarily used as a building block in the synthesis of oligosaccharides, where the pivaloyl groups serve as protecting groups and the bromide acts as a leaving group for glycosylation reactions.
