• Mass spectra of 7H-thiazolo[3, 2-a]pyridine derivatives were measured by electronimpact ionization mass spectrometry. The substituents on the phenyl group were H, p-CH3, p-OCH3, p-Cl, p-NO2. The methyl or ethyl esters were also examined. The fragmentation patterns were deduced with the aid of the shift of the peaks by substituted groups and by deuterated derivatives. And they were confirmed by metastable peaks. Substituent effect of the phenyl groups on the fragmentation was only observed in the change of intensity of fragment ions, but not observed as the change of fragmentation pathway. On the other hand, fragmentation pathway was changed by the ester groups.
