This compound is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected form of aspartic acid, where the Fmoc group protects the amino group, and the ODMAB group protects the carboxyl side chain. This protection ensures selective reactions during peptide chain assembly, preventing unwanted side reactions. It is especially valuable in synthesizing complex peptides with high precision, as it allows for the controlled incorporation of aspartic acid residues. After synthesis, the protecting groups can be removed under specific conditions to yield the desired peptide. Its application is critical in the development of pharmaceuticals, bioactive peptides, and research tools in biochemistry and molecular biology.
