 However, this specific isothiocyanate is expected to be highly unstable, and has indeed never been detected.The observed hydrolysis products when isolated glucobrassicin is degraded by myrosinase are indole-3-carbinol and thiocyanate ion (plus glucose, sulfate, and hydrogen ion), which are envisioned to result from a rapid reaction of the unstable isothiocyanate with water.However, a large number of other reaction products are known, and indole-3-carbinol is not the dominant degradation product when glucosinolate degradation takes place in crushed plant tissue or in intact plants.
