Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of chiral pharmaceuticals. Its morpholine ring and chiral center make it valuable in asymmetric synthesis, where it serves as a building block for drugs requiring high enantiomeric purity. The nitrophenyl group allows for further functionalization, enabling its use in cross-coupling reactions or reduction to aniline derivatives for drug scaffolds. Commonly applied in medicinal chemistry for optimizing stereochemistry in drug candidates.
