Isopropyl isothiocyanate Usage And Synthesis

Chemical Properties

Colorless liquid

Chemical Properties

Colorless liquid; penetrating, mustard-like aroma.

Occurrence

Reported found in Brussel sprouts, Chinese cabbage, Japanese horseradish, and wasabi.

Uses

Isopropyl isothiocyanate is used as is an antimicrobial agent. It is also used as medicinal intermediate.

Uses

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

Aroma threshold values

High strength odor, recommend smelling in a 0.01% solution or less.

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.
