Used in peptide synthesis as a building block, particularly for introducing β-(2-pyridyl)-alanine into peptide chains. It is valuable in creating peptides with specific structural or functional properties, often for research in biochemistry and drug development. The Fmoc group provides protection during synthesis, ensuring selective reactions. This compound is also employed in studies involving metal ion coordination, as the pyridyl group can interact with metals, making it useful in designing metallopeptides or studying protein-metal interactions. Its application extends to the development of bioactive peptides and enzyme inhibitors. Additionally, the 2-pyridyl group enhances stability and solubility in various solvents, making it suitable for solid-phase peptide synthesis (SPPS).
