Application:
4-Dimethylaminobenzaldehyde (CAS 100-10-7) is a mamber of the class of benzaldehydes carrying a dimethylamino substituent at position 4. 4-(Dimethylamino)benzaldehyde is a simple aldehyde which forms colorful Schiff base adducts with amines, pyrroles and indoles, and can be used to assay proteins for residues containing these functional groups. 4-(Dimethylamino)benzaldehyde is often used for the Ehrlich reaction: a test for the presence of indoles in a sample. This reagent is for detecting the indole and identify the indole-positive and indole-negative microorganisms. This reaction with indole is also exploited to indicate the presence of tryptophan residues on proteins. 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 urine bilirubin and porphobilinogen.
