Ehrlich-aldehyde reaction
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. Several Ehrlich tests use the reagent in a medical test; some are drug tests and others contribute to … See more Ehrlich reagent can be used to detect urobilinogen, which can indicate jaundice or other liver-related issues.
