Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its protected amine group and thioether functionality make it valuable in peptide-like scaffold construction, where selective reactivity and structural stability are required. Commonly employed in medicinal chemistry for building blocks in drug discovery, especially in optimizing pharmacokinetic properties through ring-containing motifs. Also utilized in solid-phase and solution-phase organic synthesis due to its compatibility with various coupling reagents and protecting group strategies.
