Identification of phase I and II metabolites of the new designer drug α‐pyrrolidinohexiophenone (α‐PHP) in human urine by liquid chromatography quadrupole time‐of‐flight mass spectrometry (LC‐QTOF‐MS)

Abstract

After publication of this article,1, the following errors were identified. A further fragment at m/z 186.1286 (C13H16N+, mass error: 4.83 ppm) may be the product of the loss from two H2O molecules and a neutral loss of C3H6. A subsequent loss of the radical fragment C4H7O2• led to another prominent radical cation at m/z 173.1198 (C12H15N•+, mass error: −0.58 ppm).
