This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a building block for constructing peptides, where the Fmoc (fluorenylmethyloxycarbonyl) group acts as a protecting group for the amino group during the synthesis process. The presence of two alanine residues makes it useful for creating specific peptide sequences that require this amino acid configuration. It is commonly employed in research and development of pharmaceuticals, biotechnology, and biochemistry for designing peptides with desired biological activities or structural properties. Its application is crucial in the production of peptide-based drugs, vaccines, and diagnostic tools.
