Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where chiral amino acid derivatives are required. Its ester and amine functionalities allow for selective chemical modifications, making it valuable in constructing complex molecules. Commonly employed in research settings for the preparation of peptide mimetics and small-molecule drug candidates. Also utilized in asymmetric synthesis due to its chiral center, enabling the production of enantiomerically pure compounds.
