The conditions under which 3, 5-dibromosalicylaldehyde undergoes coloration with amino acid were examined and the aldehyde was found to be utilizable as a reagent for determination of amino acid. Determination conditions were established for lysine, arginine, serine, and glycine and the determination was carried out on standard amino acid solution. Determinable limit was 5-100γ in neutral and basic amino acids. Acidic amino acids, proline, and hydroxyproline do not undergo this coloration.
