This compound is primarily used in peptide synthesis as a protected form of aspartic acid. The methyl ester groups help prevent unwanted reactions during the formation of peptide bonds, ensuring precise and controlled synthesis. It is particularly valuable in the production of complex peptides and proteins for research and pharmaceutical applications. Additionally, it serves as a building block in the development of bioactive peptides, which are used in drug discovery and therapeutic treatments. Its stability and ease of use make it a preferred choice in organic and medicinal chemistry laboratories.
