Will someone explain how to detect the indole-3-acetamide,indole-3-acetaldehyde, indole-3-pyruvic acid, indole-3-acetonitrile, and tryptamine in a solution by using color producing reactions? I know indole-3-acetic acid can be tested using Salkowski's reagent but don't know about others.
I need to perform colorimetric tests (qualitative/quantitative) for the detection and estimation of these derivatives.
Dear Shrawan,

Thank you sir, for your response! I know about Ehrich's reagent and in fact, I have used it along with Salkowski's Reagent (Ehmann's reagent) for the Thin layer Chromatographic detection of indole derivatives. But I'm looking for how to test indole derivatives in solutions (colorimetric test) not in the Thin Layer Chromatographic spraying method.
