This compound is primarily utilized in peptide synthesis as a protected amino acid derivative. The Z (benzyloxycarbonyl) group serves as a protective moiety for the amino group, preventing unwanted reactions during peptide bond formation. The methoxy ester (Ome) protects the carboxyl group, ensuring selective reactivity. Its application is crucial in the stepwise construction of peptides, particularly in solid-phase peptide synthesis (SPPS), where controlled deprotection and coupling are essential. It is also used in the preparation of modified peptides and peptidomimetics for research in drug discovery and biochemical studies. The HCl salt form enhances its stability and solubility, making it suitable for various organic and aqueous reaction conditions.
