Fmoc-3-Amino-3-(2-fluorophenyl)-propionic acid is primarily used in peptide synthesis. It serves as a building block for creating peptides with specific structural and functional properties. The Fmoc group protects the amino group during the synthesis process, ensuring that the peptide chain grows correctly. The 2-fluorophenyl moiety can influence the peptide's interaction with biological targets, making it valuable in designing peptides for drug development and biochemical research. This compound is particularly useful in the production of peptide-based pharmaceuticals, where precise control over peptide structure is crucial for efficacy and specificity.
