Abstract

The electron impact (EI) induced mass spectral fragmentation of seventeen, including seven newly synthesized, N‐1 and C‐6 carboxyalkyl‐ and alkoxycarbonylalkyl‐substituted derivatives of uracil and thymine was investigated. Fragmentation pathways are proposed on the basis of accurate mass and metastable transition measurements. The correlation between the intensities of the M^+^* and selected fragment ions of these compounds is discussed. The data obtained provide the basis for distinguishing isomers and metamers.
