General description

2-Ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine perchlorate is a primary metabolite of methadone.

Application

2-Ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine perchlorate has been used as a standard in the quantitative determination of of methadone and metabolites in human meconium using liquid chromatography coupled with atmospheric pressure chemical ionization tandem mass spectrometry technique (LC–APCI–MS/MS).
A metabolite of methadone, useful as a marker in GC-MS analyses.

We developed a method based on liquid chromatography coupled with tandem mass spectrometry to quantify individual enantiomers of methadone and its primary metabolite, R/S-2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolinium (EDDP), in postmortem blood and brain tissue. Samples were prepared with a Tecan Evo robotic system.
