An analytical procedure for the determination of benzoylecgonine in urine by GC/MS using a two step liquid-liquid extraction scheme has been developed. Benzoylecgonine is one of the principle metabolites of cocaine. The extraction uses a wash step prior to extraction and derivatization and requires
Hydrophilic interaction liquid chromatography-tandem mass spectrometry (HILIC-MS/MS) determination of cocaine and its metabolites benzoylecgonine, ecgonine methyl ester, and cocaethylene in hair samples.
