Used as an intermediate in peptide synthesis, particularly in the protection and coupling steps for amino acids. Its functional groups allow selective deprotection, enabling stepwise assembly of complex peptides. Commonly applied in the preparation of pharmaceutical compounds where precise amino acid sequencing is required. Stable under various reaction conditions, making it suitable for solid-phase and solution-phase synthesis. Also utilized in the development of enzyme inhibitors and bioactive molecules due to its structural compatibility with natural peptides.
