✦ Synopsis

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 -'SHI + ions of 36 2-alkylthiouracils is discussed. The data obtained create the basis for distinguishing structural isomers.
