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 ...
Herbicidal warfare is the use of substances primarily designed to destroy the plant-based ecosystem of an area. Although herbicidal warfare use chemical substances, its main purpose is to disrupt agricultural food production and/or to destroy plants which provide cover or concealment to the enemy, not to asphyxiate or poison humans and/or destroy human-made structures.
[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 ...

Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with molecular formula N(CH 3) 4 + OH −. It is commonly encountered in form of concentrated solutions in water or methanol. TMAH in solid state and its aqueous solutions are all colorless, but may be yellowish if impure.
The fleet emission average for delivery vans, trucks and big rigs is 10.17 kg (22.4 lb) CO 2 per gallon of diesel consumed. Delivery vans and trucks average about 7.8 mpg (or 1.3 kg of CO 2 per mile) while big rigs average about 5.3 mpg (or 1.92 kg of CO 2 per mile). [31]
The U.S. Food and Drug Administration is moving to ban the use of Red No. 3 dye in food products. The agency said Wednesday it is amending its color additive regulations to no longer allow the use ...
The salts are composed of the thiocyanate ion ([SCN] −) and a suitable cation (e.g., ammonium thiocyanate, [NH 4] + [SCN] −). Isothiocyanic acid forms isothiocyanates R−N=C=S, where R stands for an organyl group. Thiocyanuric acid is a stable trimer of thiocyanic acid.
