This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a protected amino acid derivative, enabling the sequential assembly of peptides with high precision. The Fmoc group provides temporary protection for the amino group during synthesis, while the tBu group protects the carboxylic acid side chain of aspartic acid. The inclusion of the pseudoproline dipeptide (Ser[PSI(Me,Me)Pro]) helps to reduce aggregation and improve solubility during the synthesis of challenging peptide sequences, such as those prone to secondary structure formation. This compound is especially valuable in the production of complex peptides for research in biochemistry, pharmaceuticals, and drug development, where controlled and efficient synthesis is critical.
