A simple, rapid and reliable method was developed to determine the concentration of etomidate [ethyl-1-(1-phenylethyl)-1 H-imidazole-5-carboxylate] in mouse brain tissue by gas chromatography-mass spectrometry (GC-MS). Ethyl 5-amino-1-phenyl-4-pyrazolecarboxylate was used as internal standard (IS) and liquid-liquid extraction using ethyl ether as
