Used as a key reagent in organic synthesis for the protection of hydroxyl groups, particularly in carbohydrate chemistry. It facilitates the formation of glycosidic bonds, enabling the synthesis of complex oligosaccharides and glycoconjugates. Its role in protecting sensitive functional groups ensures high selectivity and yield in multi-step reactions. Additionally, it is employed in the preparation of glycosyl donors, which are essential intermediates in the production of natural products and pharmaceuticals. Its stability and reactivity make it a valuable tool in the development of biologically active compounds and drug discovery.
