Phenethyl isothiocyanate is unstable in aqueous media and at low pH, and rapidly degrades to phenethylamine. Concentrations of phenethylamine, a phenethyl isothiocyanate marker, in dog plasma, were determined utilizing solid-phase extraction and gas chromatography-mass spectrometry with chemical ionization using acetone

Phenethyl isothiocyanate (PEITC) is a dietary compound present in cruciferous vegetables that has cancer-preventive properties. Our objective was to develop and validate a novel liquid chromatography-tandem mass spectrometry procedure to analyze PEITC concentrations in human plasma and urine. Following hexane

Dietary glucosinolates are under intensive investigation as precursors of cancer-preventive isothiocyanates. Quantitation of the dose and bioavailability of glucosinolates and isothiocyanates requires a comprehensive analysis of the major dietary glucosinolates, isothiocyanates, and related metabolites. We report a liquid chromatography with
