Structure elucidation of a new designer benzylpiperazine: 4-bromo-2,5-dimethoxybenzylpiperazine.
A new designer benzylpiperazine was seized in Germany for the first time. Interpreting the results of gas chromatography-mass spectroscopy (GC-MS), product ion spectroscopy (GC-MS/MS), and nuclear magnetic resonance (NMR) spectroscopy the compound was 4-bromo-2,5-dimethoxybenzylpiperazine. The structure of the new benzylpiperazine was finally proved by two-dimensional NMR correlations and by GC-MS after synthesis of two of the possible isomers from commercially available starting materials. Additionally mass spectroscopic data after liquid chromatography-mass spectroscopy (LC-MS/MS) using electrospray ionization (ESI) as well as ultraviolet (UV) spectral data of the new compound are presented. A small quantity of the new benzylpiperazine was seized in very high purity along with other also very pure designer drugs in Hamburg, Germany.
