Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of peptide-based drugs and bioactive molecules. Its protected amine group allows for selective reactions in multi-step organic syntheses, making it valuable in constructing complex amino acid derivatives. Commonly employed in solid-phase peptide synthesis and medicinal chemistry for modifying amino acid structures with high stereochemical control. Also utilized in the preparation of enzyme inhibitors and drug candidates targeting metabolic and neurological disorders.
