Metabolite Identification
Common NameMethyl isothiocyanate
DescriptionMethyl isothiocyanate, also known as methyl mustard or trapex, belongs to the class of organic compounds known as isothiocyanates. These are organic compounds containing the isothiocyanate group, an isocyanate analogue with the general formula RN=C=S. Methyl isothiocyanate is a horseradish, mustard, and pungent tasting compound. Methyl isothiocyanate has been detected, but not quantified, in cabbages and horseradish. This could make methyl isothiocyanate a potential biomarker for the consumption of these foods. Methyl isothiocyanate is a potentially toxic compound.
