Description

General description

4-(Dimethylamino)benzaldehyde is also commonly referred as Ehrlich′s reagent. Its crystal structure has been investigated by X-ray analysis. Its crystals belong to the monoclinic crystal system and exhibits space group P2₁/n. 4-(Dimethylamino)benzaldehyde exhibits dual fluorescence. Its dipole moment in various excited states has been evaluated using their electronic spectra and Bilot-Kawski theory.

Application

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

4-(Dimethylamino)benzaldehyde in micelle (sodium dodecyl sulphate) containing medium may be used for the quantification of hydroxyproline in meat samples by spectrophotometric methods.
