Identifizierung von Aminen

2,4-Dinitrophenyl derivatives of amines (DNP-amines) were investigated by thin-layer chromatography and mass spectrometry. The fragmentation of the compounds upon electron impact is discussed. The investigations show that amines in their form as DNP-derivatives can be separated by TLC except for some critical pairs. From the mass spectra of the DNP-amines the structure of an amine can be elucidated so far that a quick and reliable identification is possible by comparison with authentic material and IR spectroscopy.
