This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected form of glutamic acid, where the Fmoc group protects the amino group, and the Dmab group protects the side chain carboxyl group. This protection allows for selective deprotection and controlled assembly of peptide chains. It is especially valuable in synthesizing complex peptides where precise control over the sequence is required. The compound is commonly employed in research and pharmaceutical development to create peptides with specific biological activities or structural properties. Its use ensures high purity and efficiency in peptide production.
