4-Dimethylaminobenzaldehyde Chemical Properties,Uses,Production

Chemical Properties

White to off white crystalline powder

Uses

In 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.

Uses

Forms colored condensation products (Schiff bases) with pyrroles1 and primary amines.2

Uses

In 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.

Uses

4-(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.

Uses

Used as derivitizing agent.

Definition

ChEBI: 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 Methods

Crystallise 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.]
