| Application: | Potassium thiocyanate (KSCN) may be used for the colorimetric quantification of intracellular iron content of the superparamagnetic iron oxide (SPIO) nanoparticles. |
| Application: | Potassium thiocyanate may be used in the synthesis of the following: • α-Amino nitriles from tertiary amines. • Polysubstituted 2-aminothiazoles from vinyl azides. • Benzisothiazol-3(2H)-one derivatives from o-bromobenzamides. • Diaryl thioethers from aryl halides. |
| General description: | Potassium thiocyanate is an inorganic potassium salt. Phase transitions in potassium thiocyanate (KSCN) have been investigated by X-ray diffraction studies. The order-disorder type transition with respect to the orientation of the thiocyanate ions was identified. Its polarized infrared spectrum has been reported. It participates in the ring-opening of aziridines. The reaction was carried out in the presence of sulfated zirconia to afford the corresponding β-aminothiocyanates. |
