A spray reagent for easy identification of amino acids on thin-layer chromatography plates has been introduced. The reagent is capable of developing various distinguishable colours with many of them. A probable mechanism for such colour formation has also been proposed.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
