Ecgonine methyl ester is a major urinary metabolite of cocaine, a popular illicit drug well known as "crack" or the free base form of cocaine that can be smoked. This stable-labeled internal standard is suitable for use in cocaine testing or isotope dilution methods for GC/MS or LC/MS applications in …

Ecgonine methyl ester protects against cocaine lethality in mice. Hoffman RS(1), Kaplan JL, Hung OL, Goldfrank LR.

Benzoylecgonine (BZ) and ecgonine methyl ester (EME) are the most abundant metabolites of over 11 metabolites of cocaine as shown in Fig. 17.1 [10–13]. Cocaine is deactivated to BZ and EME primarily through deesterification (hydrolysis) in the liver. Most other metabolites are pharmacologically inactive or have very low activity. Anhydroecgonine methyl ester (AEME) results from cocaine pyrolysis and can be used as a marker for crack cocaine use.

Ecgonine methyl ester is a major urinary metabolite of cocaine, a popular illicit drug well known as "crack" or the free base form of cocaine that can be smoked.

A method for the determination of cocaine (COC), benzoylecgonine (BE), ecgonine methyl ester (EME), and ecgonine (ECG) in plasma by liquid chromatography-mass spectrometry (LC-MS-MS) was developed. The analytes were isolated from human plasma by subsequent solid-phase extraction and were separated o … ecogonine methyl ester (EME) by full scan electron impact gas chromatography/mass spectrometry, were used to evaluate the stability of EME in refrigerated and frozen conditions. After an initial quantitation (t = 0), these specimens were split and stored at either 4 degrees C or -20 degrees C. At several intervals, Ecgonine methyl ester-D3 MSDS (Chinese) This MassBank Record with Accession AU161803 contains the MS2 mass spectrum of 'Ecgonine-methyl-ester (EME)' with the InChIKey 'QIQNNBXHAYSQRY-ABIFROTESA-N'.
