|  |  | TRIMETHYLSILYL ISOTHIOCYANATE Usage And Synthesis | 
 | Chemical Properties | clear colorless to light yellow liquid |  | Uses | Trimethylsilyl isothiocyanate is used as derivatizing reagent during the synthesis of amino acid thiohydantoins. It participates in ring opening reaction of N-substituted aziridines and cyclohexene oxide. |  | Uses | Trimethylsilyl isothiocyanate was used as derivatizing reagent during the synthesis of amino acid thiohydantoins. |  | General Description | Trimethylsilyl isothiocyanate (TMS-ITC) reacts with fullerene-mixed peroxide C60(O)(OOtBu)4 to yield isothiocyanate derivative C60(NCS)(OH)(OOtBu)4. TMS-ITC undergoes condensation with ethyl 2-benzylamino-5-methyl-3-phenylcyclopent-1-enecarboxylate to yield 1-benzyl-5-methyl-7-phenyl-2-thioxo-1,2,3,5,6,7-hexahydrocyclopentapyrimidin-4-one. It participates in ring opening reaction of N-substituted aziridines and cyclohexene oxide. |  | Purification Methods | The 1H NMR spectrum should have only one peak; if not purify it by repeated fractionation in an all-glass system using a 50cm (4mm internal diameter) column without packing.
