A Note On the Chromotropic Acid Reagent for 2,4–D Analysis
Published online by Cambridge University Press: 12 June 2017
Extract
One of the more common methods of analysis for 2,4–dichlorophenoxyacetic acid (2,4,–D) is the one using chromotropic acid as the color developing reagent (1). In this laboratory it was found that it was difficult to obtain relatively pure chromotropic acid or its disodium salt. As an approach to the preparation of a purer compound, several experiments were tried.
