Z-Asp(OMe)-OH is widely used in peptide synthesis as a protected form of aspartic acid. Its primary application is in the construction of peptides where aspartic acid needs to be incorporated without unwanted side reactions. The methoxy (OMe) group protects the carboxylic acid functionality, ensuring selective reactions at other sites during peptide chain elongation. This compound is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase methods, where protecting groups are essential for controlling the sequence and integrity of the peptide. Additionally, it is utilized in the development of pharmaceuticals and bioactive peptides, where precise amino acid incorporation is critical for maintaining the desired biological activity. Its stability and ease of deprotection make it a reliable choice for researchers and industrial applications in peptide chemistry.
