Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules containing azetidine rings. Its protected amine group (Boc) allows for selective reactions at other functional sites, making it valuable in multi-step organic synthesis. The hydroxymethyl and methyl substituents provide structural diversity, enabling fine-tuning of molecular properties in drug design. Commonly employed in medicinal chemistry for constructing small molecule therapeutics, especially in protease inhibitors and CNS-active agents.
