Abstract: This report describes the results of a study of the electron impact mass spectrometry behaviour of 20 new compounds of a series of 3‐[3‐(4‐aryl)‐1,2,4‐oxadiazole‐5‐yl] acyl arylaldehyde hydrazone derivatives. The most relevant possible fragmentation patterns of this class of compounds under electron impact are outlined.
