Used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a building block for incorporating ornithine residues into peptide chains. The Fmoc group provides protection for the amino group during synthesis, ensuring selective reactions. After synthesis, the Fmoc group can be removed under mild conditions, allowing further peptide chain elongation. This compound is essential in producing peptides for research, drug development, and biochemical studies. It is also utilized in creating peptides with specific structural or functional properties, such as those used in antimicrobial or therapeutic applications.
