Used in biochemical research as a specific inhibitor to study fucosylation processes in glycoproteins and glycolipids. It helps in understanding the role of fucose in cell signaling and immune responses. Also employed in the synthesis of complex carbohydrates and glycoconjugates for therapeutic and diagnostic applications. Its application extends to the development of vaccines and cancer research, where fucose-containing structures are targeted. Additionally, it serves as a tool in enzymatic studies to explore the substrate specificity of fucosidases and fucosyltransferases.
