First enantioselective determination of N-ethylpentedrone and its major phase-1 metabolites using supercritical fluid chromatography coupled with tandem mass spectrometry and its application to human oral fluid and urine samples
{{output}}
The enantioselective bioanalysis of synthetic cathinones and their metabolites remains analytically challenging. Due to the basic nature of these compounds, mobile phases with elevated pH are preferable for their analysis in high-performance liquid chromatogra... ...
