General description

Benzyl isothiocyanate is a naturally-occurring constituent of cruciferous vegetables. It has antibacterial properties and its metabolism in man has been investigated. It inhibits chemically induced cancer in animal models.

Application

Benzyl isothiocyanate has been used in the preparation of S-(N-benzylthiocarbamoyl)-L-glutathione and S-(N-benzylthiocarbamoyl)-L-cysteine.
Benzyl isothiocyanate can be used as a reactant to synthesize:
  • N

  • -benzylthioureas by reacting with various amines.
  • N-benzyl-O-alkyl carbamates by treating with long-chain alcohols.
  • 3-mercapto-1,2,4-triazole building block by reacting with formylhydrazine via acyl thiosemicarbazide intermediate formation.
  • S-(N-benzylthiocarbamoyl)-L-glutathione and S-(N-benzylthiocarbamoyl)-L-cysteine.
