  Simultaneous Quantitative Determination of Synthetic Cathinone Enantiomers in Urine by GC-NCI-MS/MS using Menthylchloroformate as Chiral Derivatization Reagent

  Development and validation of a new analytical method for enantioseparation and quantitation of synthetic cathinones is reported using a chiral derivatization agent (CDA) and GC-MS triple quadrupole mass spectrometry with negative chemical ionization (NCI) mode. Indirect separation of ten synthetic cathinone compounds has been achieved using a commercially available optically pure CDA called (1R)-(-)-menthylchloroformate (MCF). MCF was capable of converting synthetic cathinone enantiomers into diastereoisomers, which were later separated with good resolution on an ultra-inert 60 m achiral stationary phase column. An internal standard (IS), 3-methylmethcathinone (3-MMC) was used for quantitation of synthetic cathinone diastereoisomers. Method validation in terms of calibration curve linearity, sensitivity in terms of limits of detections (LODs), limits of quantitation (.. View More»
