Screening and confirmation methods of the major urinary metabolite of finasteride–carboxy-finasteride by liquid chromatography–mass spectrometry and liquid chromatography–tandem mass spectrometry
Screening and confirmation methods of the major urinary metabolite of finasteride–carboxy-finasteride for doping control purpose were developed. Liquid–liquid extraction was adopted for the sample preparation. Analytes were detected by positive electrospray ionization in single quadrupole and triple...
