[7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system. [11] [12] Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter. [13] Iodine is an essential component of thyroxine. Since thiocyanates will ...
The 1:1 complex of thiocyanate and iron is deeply red. The effect was first reported in 1826. [15] The structure of this species has never been confirmed by X-ray crystallography. The test is largely archaic. Copper(I) thiocyanate is a reagent for the conversion of aryl diazonium salts to arylthiocyanates, a version of the Sandmeyer reaction.
Mercury(II) thiocyanate (Hg(SCN) 2) is an inorganic chemical compound, the coordination complex of Hg 2+ and the thiocyanate anion. It is a white powder. It is a white powder. It will produce a large, winding "snake" when ignited, an effect known as the Pharaoh's serpent .
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
In methyl thiocyanate, N≡C and C−S distances are 116 and 176 pm. By contrast, N=C and C=S distances are 117 and 158 pm in isothiocyanates. [7] Typical bond angles for C−S−C are 100°. [3] By contrast C−N=C in aryl isothiocyanates is 165°. Again, the thiocyanate isomers are quite different with C−S−C angle near 100°.

TMSNCS is useful reagent in organic chemistry. It is an ambident nucleophile, able to react with various alkyl halides, acetals, aldehydes, unsaturated compounds, aziridines, oxiranes, polycyclic aromatic hydrocarbons, and acetylated hexoses to form either thiocyanate or isothiocyanate structures.
