## Abstract The mass spectral fragmentation of twelve new 2‐alkoxycarbonylalkylthio substituted derivatives of uracils is discussed and fragmentation pathways, elucidation of which were assisted by accurate mass measurements and metastable transitions are proposed. It has been found that the basic

The mass spectral fragmentations of eight 2-alkylthiouracils with C,,,, C I 2 , C,, and C,, in the alkylthio group were investigated. Fragmentation pathways are proposed on the basis of accurate mass and metastable transition measurements. The correlation between the intensities of the M" and [ M -'
