Abstract : Electrospray ionization quadrupole time-of-flight (ESI-QqToF) mass spectra of naltrindole hydrochloride 1, naltriben mesylate 2, and naltrexone hydrochloride 3, a common series of morphine opiate receptor antagonists, were recorded using different declustering potentials. Low-energy collision-induced dissociation (CID) MS/MS experiments established the fragmentation routes of these compounds. In addition, re-confirmation of the various established fragmentation routes was effected by conducting a series of ESI-CID-QqTof-MS/MS experiments using non-conventional quasi MSⁿ (up to MS⁸) product ion scans, which were initiated by CID in the atmospheric pressure/vacuum interface using a higher declustering potential. Precursor ion scan analyses were also performed with a conventional quadrupole-hexapole-quadrupole tandem mass spectrometer and allowed the confirmation of the genesis of some diagnostic ions.
