3,4-Difluorophenylalanine（Cat No.:I043294）is a fluorinated aromatic amino acid used in peptide synthesis, pharmaceutical research, and protein engineering. As a phenylalanine analog, it introduces fluorine atoms at the 3- and 4-positions, enhancing metabolic stability, hydrophobicity, and bioactivity. This modification is valuable in drug discovery, enzyme inhibition studies, and structural biology, where fluorine can alter protein-ligand interactions. It is commonly used in fluorinated peptide drug design, metabolic pathway investigations, and structural probing of proteins, making it a key tool in medicinal chemistry and biochemical research.
