Used as a key intermediate in organic synthesis, particularly in the preparation of β-amino acids and modified peptides. Its strained aziridine ring allows for ring-opening reactions with nucleophiles, enabling the introduction of functionalized amine groups in pharmaceuticals and bioactive molecules. Commonly employed in the development of enzyme inhibitors and antibiotics due to its ability to mimic natural amino acid structures. Also utilized in the synthesis of chiral auxiliaries and ligands for asymmetric catalysis.
