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

4-(Dimethylamino)benzaldehyde in micelle (sodium dodecyl sulphate) containing medium may be used for the quantification of hydroxyproline in meat samples by spectrophotometric methods.
Forms colored condensation products (Schiff bases) with pyrroles and primary amines.
