Used in peptide synthesis as a dipeptide derivative (H-Ala-Val-OH), particularly in the preparation of bioactive peptides with specific stereochemistry. Its trifluoroacetate salt form enhances solubility and stability during solid-phase or fragment coupling synthesis. Commonly employed in pharmaceutical research for developing enzyme inhibitors and receptor ligands, especially where chiral purity is critical. Also utilized in the production of synthetic analogs of natural peptides for structure-activity relationship studies.
