Used in peptide synthesis as a protected dipeptide building block, enabling stepwise construction of complex peptides. The Cbz and benzyl ester groups act as protecting groups for the amino and carboxyl termini, respectively, allowing selective deprotection and coupling reactions. Commonly employed in the preparation of biologically active peptides and enzyme substrates, particularly those involving tyrosine-containing sequences. Its stability under various reaction conditions makes it suitable for solid-phase and solution-phase peptide synthesis. Also utilized in the development of pharmaceutical intermediates and biochemical research tools.
