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°.
[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 ...
By contrast, in methyl thiocyanate, N≡C and C−S distances are 116 and 176 pm. Typical bond angles for C−N=C in aryl isothiocyanates are near 165°. Again, the thiocyanate isomers are quite different with C−S−C angle near 100°. [3] In both isomers the SCN angle approaches 180°.
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.
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.
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 ]
Urban planners are increasingly exploring nature-based solutions such as temporary lagoons, which can store excess water during heavy rains, and green roofs that help to absorb rain and cool down ...
Potassium thiocyanate is the chemical compound with the molecular formula KSCN. It is an important salt of the thiocyanate anion , one of the pseudohalides . The compound has a low melting point relative to most other inorganic salts.
