Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its hydroxyl and protected amine functional groups allow for selective chemical modifications, making it valuable in constructing complex organic structures. Commonly employed in medicinal chemistry for optimizing solubility, stability, and binding properties of potential therapeutics. Also utilized in the preparation of cyclobutane-based scaffolds, which are increasingly explored for their conformational rigidity and metabolic resistance in drug design.
