Used primarily as a key intermediate in the synthesis of pharmaceuticals, especially in the development of bioactive molecules and prodrugs. Its structure supports conjugation with other compounds, making it valuable in creating targeted drug delivery systems. Commonly employed in the preparation of peptide mimetics and enzyme inhibitors due to its ability to mimic natural substrates. Also utilized in polymer chemistry for modifying surfaces and building functionalized biomaterials. Its reactivity allows for easy incorporation into larger molecular frameworks, particularly in medicinal chemistry research and development.
