Thiocyanate complexes are not widely used commercially. Possibly the oldest application of thiocyanate complexes was the use of thiocyanate as a test for ferric ions in aqueous solution. [15] The reverse was also used: testing for the presence of thiocyanate by the addition of ferric salts. The 1:1 complex of thiocyanate and iron is deeply red.
Thiocyanate [6] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. [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.
This behavior is visualized by the color change brought about by reaction with thiocyanate: [Fe(H 2 O) 6] 3+ + SCN − ⇌ [Fe(SCN)(H 2 O) 5] 2+ + H 2 O. Whereas [Fe(H 2 O) 6] 3+ is nearly colorless, [Fe(SCN)(H 2 O) 5] 2+ is deep red. While iron(III) aquo complexes tend to convert to polymeric oxy-hydroxides, iron(III) complexes with other ...
Several synthesis routes exist, [3] the most common being the reaction between alkyl halides and alkali thiocyanate in aqueous media. [4] Illustrative is the preparation of isopropyl thiocyanate by treatment of isopropyl bromide with sodium thiocyanate in boiling ethanol. [5]
The mixed reactants are delivered into an observation cell (flow cell) where the reaction can be monitored spectrophotometrically, typically using techniques such as absorbance, fluorescence, fluorescence anisotropy, or circular dichroism. It is increasingly common to combine several of these techniques for more comprehensive analysis. [6]
Aqueous ferric thiocyanate (Fe(SCN)n) hydrate mix. Intravenous therapy is a type of parenteral medication. IV iron infusion is a method of delivering a mixed solution of iron and saline from a drip through a needle directly into the vein and bloodstream. [14]
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 ...
A thiocyanate hydrolase (EC 3.5.5.8) is an enzyme belonging to the family of hydrolases. The systematic name of this enzyme class is thiocyanate aminohydrolase. This enzyme catalyzes the chemical reaction: SCN − + 2 H 2 O + H + ⇌ SCO + NH 3. The mechanism is proposed to involve a metal thiocyanate complex.
