[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 ...
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°.

Thiocyanic acid has been observed spectroscopically. [12] The salts and esters of thiocyanic acid are known as thiocyanates. The salts are composed of the thiocyanate ion ([SCN] −) and a suitable cation (e.g., potassium thiocyanate, KSCN). The esters of thiocyanic acid have the general structure R−S−C≡N, where R stands for an organyl group.

Fluorescein isothiocyanate (FITC) is a derivative of fluorescein used in wide-ranging applications [1] [2] including flow cytometry.First described in 1942, [3] FITC is the original fluorescein molecule functionalized with an isothiocyanate reactive group (−N=C=S), replacing a hydrogen atom on the bottom ring of the structure.
Sodium thiocyanate (sometimes called sodium sulphocyanide) is the chemical compound with the formula NaSCN. This colorless deliquescent salt is one of the main sources of the thiocyanate anion . As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals . [ 2 ]
Thiocyanogen, (SCN) 2, is a pseudohalogen derived from the pseudohalide thiocyanate, [SCN] −, with behavior intermediate between dibromine and diiodine. [2] This hexatomic compound exhibits C 2 point group symmetry and has the connectivity NCS-SCN. [3] In the lungs, lactoperoxidase may oxidize thiocyanate to thiocyanogen [4] or ...
