描述
Phenethyl isothiocyanate, also known as peitc or beta-phenylethyl isothiocyanic acid, belongs to benzene and substituted derivatives class of compounds. Those are aromatic compounds containing one monocyclic ring system consisting of benzene. Phenethyl isothiocyanate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Phenethyl isothiocyanate is a bitter, gooseberry, and green tasting compound and can be found in a number of food items such as herbs and spices, brassicas, horseradish, and cabbage, which makes phenethyl isothiocyanate a potential biomarker for the consumption of these food products. Phenethyl isothiocyanate (PEITC) is a naturally occurring isothiocyanate whose precursor, gluconasturtiin is found in some cruciferous vegetables, especially watercress .
