Used as a chiral building block in pharmaceutical synthesis, particularly in the production of bioactive molecules and drug intermediates. Its protected diol and primary amine functionalities allow selective reactions in multistep organic syntheses. Commonly employed in the development of antiviral and antibacterial agents due to its structural compatibility with nucleoside analogs. Also utilized in the preparation of specialty polymers and ligands for catalysis, where stereochemistry plays a critical role in performance.
