Following the research work on mass spectra of thiophenic compounds,'-' we report here the electron impact mass spectra at 70eV of some 2-and 4-substituted thiophene-3-carboxylic acids (1-23) with the aim of comparing the fragmentations observed with those of the corresponding 3-substituted thiophen
