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.
A non-ozone-producing xenon arc lamp is commonly used for most general stopped-flow experiments above 250 nm. Broad-spectrum xenon lamps are highly versatile, allowing users to select virtually any wavelength for absorbance or fluorescence studies, making them ideal for applications such as monitoring structural changes in proteins over time.
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.
Aryl thiocyanates are traditionally produced by the Sandmeyer reaction, which involves combining copper(I) thiocyanate and diazonium salts: [3] [ArN 2]BF 4 + CuSCN → ArSCN + CuBF 4 + N 2. Some arylthiocyanates can also often be obtained by thiocyanogenation, i.e. the reaction of thiocyanogen. This reaction is favored for electron-rich ...
The formation of Fe(III)-EDTA (FeY) − can be described as follows: FeSO 4 ∙7H 2 O + K 2 H 2 Y + 1/4 O 2 → K[FeY(H 2 O)]. H 2 O + KHSO 4 + 5.5 H 2 O (1) [8]. Iron chelate has also been used as a bait in the chemical control of slugs, snails and slaters in agriculture in Australia and New Zealand.
However, iron tends to form highly insoluble iron(III) oxides/hydroxides in aerobic environment, especially in calcareous soils. Bacteria and grasses can thrive in such environments by secreting compounds called siderophores that form soluble complexes with iron(III), that can be reabsorbed into the cell.
The free radicals generated by this process engage in secondary reactions. For example, the hydroxyl is a powerful, non-selective oxidant. [6] Oxidation of an organic compound by Fenton's reagent is rapid and exothermic and results in the oxidation of contaminants to primarily carbon dioxide and water.
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.
