Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals. Its structure supports the development of nitrogen-containing heterocycles, which are common in drug molecules. The hydroxyl and tosyl groups allow for selective functionalization, making it valuable in medicinal chemistry for building complex molecules with potential antiviral, antibacterial, or central nervous system activity. Also employed in the preparation of azetidine-based scaffolds for use in drug discovery programs.
