The electron impact (EI) induced massspectral fragmentation of seventeen, including seven newly synthesized, N-1 and C-6carboxyalkyl- and alkoxycarbonylalkyl-substitutedderivatives 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
