Common Name | Isobutyl isothiocyanate |

Description | Isobutyl isothiocyanate 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. Isobutyl isothiocyanate is a green tasting compound. Isobutyl isothiocyanate is found, on average, in the highest concentration within soft-necked garlics (Allium sativum L. var. sativum). Isobutyl isothiocyanate has also been detected, but not quantified in, cauliflowers (Brassica oleracea var. botrytis). This could make isobutyl isothiocyanate a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Isobutyl isothiocyanate. |
