Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of beta-amino acid-based drugs. It serves as a building block in peptidomimetic compounds, helping to enhance metabolic stability and bioavailability in drug design. Also applied in the preparation of specialty organic compounds for research in medicinal chemistry and biochemistry. Its nitrophenyl group allows for easy detection and monitoring in reactions, making it valuable in laboratory studies involving conjugation or labeling.
