[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 ...
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 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.
For example, tetramethylammonium thiocyanate may be prepared from ammonium thiocyanate as follows: [7] NMe 4 + OH − + NH 4 + SCN − → NMe 4 + SCN − + NH 3 + H 2 O. TMAH and many other TMA salts containing simple anions thermally decompose into trimethylamine. [8] Dimethyl ether is a major decomposition product rather than methanol. [9 ...

Ammonium thiocyanate is used in the manufacture of herbicides, thiourea, and transparent artificial resins; in matches; as a stabilizing agent in photography; in various rustproofing compositions; as an adjuvant in textile dyeing and printing; as a tracer in oil fields; in the separation of hafnium from zirconium (important for the production of hafnium-free zircalloy for use in nuclear fuel ...
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°.
