4-Dimethylaminobenzaldehyde Usage And Synthesis
Chemical Properties4-Dimethylaminobenzaldehyde is white to off white crystalline powder
UsesIn the presence of oxygen, some bacteria, like E.coli, are able to split tryptophan into indole and alpha-aminopropionic acid. This reagent is for detecting the indole and identify the indole-positive and indole-negative microorganisms.
UsesForms colored condensation products (Schiff bases) with pyrroles1 and primary amines.2
UsesIn the presence of oxygen, some bacteria, like E. coli, are able to split tryptophan into indole and α-aminopropionic acid. This reagent is for detecting the indole and identifying the indole-positive and indole-negative microorganisms.
Uses4-(Dimethylamino)benzaldehyde is used in Ehrlich's reagent for spectrophotometric determination of hydrazine as it reacts to form azo dyes. 4-(Dimethylamino)benzaldehyde is used for determination of u rine bilirubin and porphobilinogen.
UsesUsed as derivitizing agent.
Definition4-Dimethylaminobenzaldehyde is a mamber of the class of benzaldehydes carrying a dimethylamino substituent at position 4. Used as an indicator for detection of indoles and hydrazine.

Purification MethodsCrystallise DMAB from water, hexane, or from EtOH (2mL/g), after charcoal treatment, by adding excess of water. Alternatively dissolve it in aqueous acetic acid, filter, and precipitate it with ammonia. Finally recrystallise it from EtOH. It is used for the detection of pyrroles [Iyer et al. J Org Chem 59 6038 1994]. [Beilstein 14 IV 51.]
