Characterization of forced degradation products of toloxatone by LC-ESI-MS/MS.

Forced degradation of toloxatone in solutions under basic, acidic, neutral, photo UV-VIS, photo UVC and oxidative stress conditions was investigated and structural elucidation of its degradation products was performed with the use of UHPLC system coupled ESI-Q-TOF mass spectrometer. Eight degradation products were found and their masses and formulas were obtained with high accuracy (0.09-3.
