[SCN]− is one of the pseudohalides, due to the similarity of its reactions to that of halide ions. Since thiocyanates will decrease iodide transport into the thyroid follicular cell, they will decrease the amount of thyroxine produced by the thyroid gland. Thus this chemical is often used to create the effect of 'stigmata'. The determination of Co(II) in the presence of Fe(III) is possible by adding KF to the solution, which forms uncoloured, very stable complexes with Fe(III), which no longer react with SCN−. 4 (H332) Aquatic Chronic 3 (H412) (EUH032) Xn; R20/21/22 R32 R52-53 For the full text of the R-phrases and H-Statements mentioned in this Section, … [10][11], Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter.

Precautionary Statements: Prevention: Not applicable. Signal Word: Not applicable. Thiocyanate is produced by the reaction of elemental sulfur or thiosulfate with cyanide: The second reaction is catalyzed by thiosulfate sulfurtransferase, a hepatic mitochondrial enzyme, and by other sulfur transferases, which together are responsible for around 80% of cyanide metabolism in the body.[1]. Ion adsorption to aqueous interfaces involving complex organic molecules is relevant to biology in connection with the familiar but incompletely understood Hofmeister effects.
