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.
Forms colored condensation products (Schiff bases) with pyrroles and primary amines.

Duchenne muscular dystrophy was initially described as a myosclerosis because of the conspicuous progression of interstitial fibrosis. Using the mdx mouse homologue, we have shown previously that the accumulation of intramuscular collagen is profoundly influenced by the presence or absence

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

The Ehrlich reaction was optimized to determine the formation of pyrrolized phospholipids in edible oils in an attempt to understand the color reversion produced during the deodorization of poorly degummed edible oils. The procedure consisted of the treatment of the
