Mass spectra of 4-trifluoromethylpteridine and nine of its derivatives are recorded. Electron impact induced fragmentations of 4-trifluoromethylpteridine and its 2-chloro-, 7-methyl-and 6,7-dimethyl-derivatives resemble those of pteridine and simple methylpteridines except that loss of a trifluorome
