Ehrlich's reagent or Ehrlich reagent is a reagent containing p-dimethylaminobenzaldehyde (DMAB) and thus can act as an indicator to presumptively identify indoles and urobilinogen
Ehrlich's dimethylaminobenzaldehyde reagent reacts with porphobilinogen to produce a pink aldehyde compound, which can be differentiated from that produced by urobilinogen by the fact that the porphobilinogen compound is insoluble in chloroform.
