Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of peptidomimetic drugs. Its protected amine and carboxylic acid functionalities make it suitable for solid-phase and solution-phase peptide synthesis. The methoxy group on the side chain can serve as a functional handle for further modification or as a structural mimic in bioactive molecules. Commonly employed in the preparation of enzyme inhibitors and drug candidates targeting metabolic and neurological disorders.
