描述
应用 |
测定吲哚、粪臭素、尿蓝母、色氨酸、白蛋白、过氧化氢、胂凡钠明、邻氨基苯甲酸、安替比林麦角碱等,还用以区别血清发疹和腥红热。制造染料。 Forms colored condensation products (Schiff bases) with pyrroles and primary amines 4-(Dimethylamino)benzaldehyde has been used in the preparation of trans-4-dimethylamino-4′-nitrostilbene. Forms colored condensation products (Schiff bases) with pyrroles and primary amines. |
生化机理 | 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 reaction with indole is also exploited to indicate the presence of tryptophan residues on proteins. |
