Used as an intermediate in the synthesis of complex carbohydrates and glycosyl donors in organic chemistry. Its peracetylated structure enhances stability and solubility in organic solvents, making it valuable for glycosylation reactions. Commonly employed in the preparation of oligosaccharides for pharmaceutical research, including vaccine development and studies on cell surface recognition. Also serves as a protected form of D-cellopentose in the construction of cellulose analogs and bioactive molecules.
