Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) containing imidazolidine or heterocyclic moieties. Its protected amine group and carbonyl functionality make it valuable in multi-step organic synthesis, especially for constructing nitrogen-containing rings found in bioactive molecules. Commonly employed in medicinal chemistry for the preparation of antihypertensive agents, enzyme inhibitors, and central nervous system modulators. Its stability and selective reactivity support use in solid-phase and solution-phase peptide-like synthesis.
