Abstract

EI induced mass spectral fragmentations of twelve new hydrazones of 2‐(3‐ and 4‐)‐pyridinecarboxaldehydes and hydrazides of (E)‐stilbenyloxyacetic acid as well as N‐(E)‐stilbenyloxyalkylcarbonyl substituted amino acids were investigated. Fragmentations pathways are proposed on the basis of accurate mass and B/E linked scan spectra measurements. The correlation between the intensities of M^+.^ and the selected fragment ions of these compounds is discussed. The data obtained create the basis for distinguishing isomers.
