General description

4-(Dimethylamino)benzaldehydeis an organic carbonyl compound containing amino and aldehyde groups. The compound is used in Ehrlich and Kovac′s reagents to test indole.4-(Dimethylamino)benzaldehyde is used to prepare aldehydes from Grignard reagents. In addition, it is used as a color test reagent for pyrroles, primary amines, and hydrazines.

Application

4-(Dimethylamino)benzaldehyde was used in the chitinase assay.

4-(Dimethylamino)benzaldehyde is used:
  • In the synthesis of azo-azomethine dyes by condensation reaction.
  • As a reagent in the synthesis of molecular adduct 4DMAB4NP (4-(dimethylamino)benzaldehyde 4-nitrophenol) by reacting with 4-nitrophenol.
  • In the preparation of Schiff base.
Forms colored condensation products (Schiff bases) with pyrroles and primary amines.
