Quantification of Synthetic Cathinones in Rat Brain Using HILIC-ESI-MS/MS.

The abuse of synthetic cathinones, formerly marketed as "bath salts", has emerged over the last decade. Three common drugs in this class include 3,4-methylenedioxypyrovalerone (MDPV), 4-methylmethcathinone (mephedrone), and 3,4-methylenedioxymethcathinone (methylone). An LC-MS/MS method has been developed and validated for the simultaneous quantification of MDPV, mephedrone, and methylone in brain tissue.
