The mass spectrometric behavior of 21 thiazide-based compounds after electrospray ionization in the negative ion mode and collision-induced dissociation was investigated on a triple-stage quadrupole mass spectrometer. The mass spectra show individual and common fragmentation patterns, the generations of which
