4-Chloro-L-phenylalanine(CAT: M058245) is a synthetic halogenated amino acid analog of L-phenylalanine, featuring a chlorine atom at the para position of the aromatic ring. It serves as a useful biochemical tool in studies of protein biosynthesis, enzyme specificity, and metabolic pathway modulation. This compound is commonly used to inhibit phenylalanine hydroxylase and to trace aromatic amino acid metabolism in cell and animal models. Its structural similarity to natural phenylalanine allows selective incorporation or competitive inhibition in peptide synthesis and functional assays. Supplied at high purity, 4-Chloro-L-phenylalanine is ideal for research in neuroscience, metabolism, and synthetic biology.
