Chemical Information
FooDB NameIsopropyl isothiocyanate
DescriptionIsopropyl isothiocyanate is a member of the class of compounds known as isothiocyanates. Isothiocyanates are organic compounds containing the isothiocyanate group, an isocyanate analogue with the general formula RN=C=S. Isopropyl isothiocyanate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Isopropyl isothiocyanate is a mustard and pungent tasting compound found in brussel sprouts, chinese mustard, and horseradish, which makes isopropyl isothiocyanate a potential biomarker for the consumption of these food products.
