General description

Isopropyl isothiocyanate is an isothiocyanate derivative. It has been identified as one of the volatile components in the following:
  • seed kernel and leaf of Moringa peregrina (Forssk.) Fiori, Agricolt1
  • essential oil isolated from Upland Wasabi
  • hydrodistillates of hedge mustard (Sysimbrium officinale)

Molecular conformations of isopropyl isothiocyanate in gas phase have been determined by electron diffraction studies. It has been synthesized by employing isopropyl amine as a starting reagent.

Application

Isopropyl isothiocyanate may be used to synthesize 4-bromo-5,6-dichloro-2-isopropylaminobenzimidazole.
