Abstract

For metabolic studies the fragmentation of a novel endothelin receptor antagonist, Bosentan, was investigated using ionspray tandem mass spectrometry. Bosentan belongs to the sulphonamide class and a complicated and unexpected fragmentation at low energy, involving a radical fragmentation of an even-electron ion at the sulphonamide bond, is reported.
