Separation and determination of chlorophenylpiperazine isomers in confiscated pills by capillary electrophoresis

- CE method for determination of chlorophenylpiperazine isomers in pills is proposed.
- Influence of various cyclodextrins on separation was studied.
- Neither ortho nor para isomers were found in Brazilian confiscated pills.
- Amount of meta isomer in Brazilian pills corresponds to amount found in European pills.
- Method allows identification of CPP and other drugs of abuse in confiscated pills.
