This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Fmoc (fluorenylmethyloxycarbonyl) group acts as a temporary protecting group for the amine functionality. The acetyl (Ac) group protects the side chain amine of the Dab (diaminobutyric acid) residue, ensuring selective reactions during peptide chain assembly. Its application is crucial in the production of complex peptides, especially those requiring precise control over the incorporation of specific amino acids. It is widely employed in pharmaceutical research, drug development, and the synthesis of bioactive peptides for therapeutic and diagnostic purposes.
