HR-MS/MS spectra of methoxyacetylfentanyl and selected phase I metabolites. The spectra with proposed structures, retention times (RT), detected in rat urine (RU) and/or pooled human S9 fraction incubations (S9), and predominant fragmentation patterns of methoxyacetylfentanyl and metabolites are arranged according to their presentation in the text.
