Metabolite Identification
Common Name5-Isothiocyanato-1-pentene
Description5-Isothiocyanato-1-pentene 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. 5-Isothiocyanato-1-pentene is a horseradish and mustard tasting compound. 5-Isothiocyanato-1-pentene has been detected, but not quantified in, several different foods, such as white cabbages (Brassica oleracea L. var. capitata L. f. alba DC.), horseradishes (Armoracia rusticana), rocket salad (ssp.), wasabis (Wasabia japonica), and brassicas. This could make 5-isothiocyanato-1-pentene a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5-Isothiocyanato-1-pentene.
