✦ Synopsis

Abstract

Collision induced dissociation of the carbon cage compounds cubane, kepone and mirex breaks the cage structures. The energy available for bond breaking is thus not less than about 9 eV, and the time between energy acquisition and subsequent unimolecular fragmentation is long enough that the available energy can be concentrated in three bonds to the same carbon atom. Collision induced dissociation mass‐analyzed ion kinetic energy spectra of [C~5~Cl~6~]^+˙^ from mirex and from hexachlorocyclopentadiene are virtually identical, and similar for [C~6~H~6~]^+˙^ ions from cubane and benzene.

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
