Thiocyanate (also known as rhodanide) is the anion [SCN]−. It is the conjugate base of thiocyanic acid. Common derivatives include the colourless salts potassium thiocyanate and sodium thiocyanate. Organic compounds containing the functional group SCN are also called thiocyanates. Mercury(II) thiocyanate was formerly used in pyrotechnics.
Thiocyanate is analogous to the cyanate ion, [OCN]−, wherein oxygen is replaced by sulfur. [SCN]− is one of the pseudohalides, due to the similarity of its reactions to that of halide ions. Thiocyanate used to be known as rhodanide (from a Greek word for rose) because of the red colour of its complexes with iron. Thiocyanate is produced by the reaction of elemental sulfur or thiosulfate with cyanide
Thiocyanate[4] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase.[5][6][7] Thus the complete absence of thiocyanate[8] or reduced thiocyanate[9] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.[10][11]
Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter.[12] Iodine is an essential component of thyroxine. Since thiocyanates will decrease iodide transport into the thyroid follicular cell, they will decrease the amount of thyroxine produced by the thyroid gland. As such, foodstuffs containing thiocyanate are best avoided by Iodide deficient hypothyroid patients.[13]
In the early 20th century, thiocyanate was used in the treatment of hypertension, but it is no longer used because of associated toxicity.[14] Sodium nitroprusside, a metabolite of which is thiocyanate, is however still used for the treatment of a hypertensive emergency. Rhodanese catalyzes the reaction of sodium nitroprusside with thiosulfate to form the metabolite thiocyanate

BCJ52 series explosion-proof emergency lights maintenance 1, fire emergency lights should be installed or stored in a dry, ventilated and non-corrosive place.
2. When using fire emergency lights, you should try to avoid being hit and knocked.
3. Check the running status of the lamps regularly every month, and always pay attention to whether the working indicator lights work in the normal state.
4. In normal use, charge the lamp once every six months to avoid early failure of the battery.
5. When the lamps are not used for a long time, the batteries should be discharged and vented. When the lamps are re-worked, they must be charged for about 18-24 hours before the lamps can work normally.
6, the product in order to better protect the light source and reflective light from dust, specifically set a beautiful dust cap on the lamp (can not be used).
BCJ52 series explosion-proof emergency lights use matters needing attention:
1. When the light is transported, it should be installed in the equipped carton and be equipped with foam shock absorption.
2. When installing the lamp, the lamp should be safely grounded.
3, when used, the surface of the lamp has a certain temperature rise, which is a normal phenomenon; the temperature of the center of the transparent part is relatively high and must not be touched.
4. When maintaining the lamp, you must disconnect the power supply.
