Application

4-(Dimethylamino)benzaldehyde (DMAB or Ehrlich’s reagent) has been used as a color reagent for the determination of hydroxyproline level.It forms colored condensation products (Schiff bases) with pyrroles and primary amines. DMAB is also suitable as a reagent to develop latent fingermarks on paper surfaces yielding impressions that are both colored and photoluminescent.

A simple colorimetric method for the differentiation of indoleacetic acid (IAA) and indolebutyric acid (IBA) in plant samples is described. The color change is based upon the reaction between the auxins and p-(dimethylamino)benzaldehyde (PDAB, Ehrlich reagent) following the electrophilic substitution
