Sodium cyanide is a compound with the formula Na C N and the structure Na + − C≡N. It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals. It is a moderately strong base.
Among the most toxic cyanides are hydrogen cyanide (HCN), sodium cyanide (NaCN), potassium cyanide (KCN), and calcium cyanide (Ca(CN) 2). The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa 3), the fourth complex of the electron transport chain found in the inner membrane of the mitochondria of eukaryotic ...
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
The nature of the poison used is also contested, with the book suggesting that a non-lethal chemical may have been used instead of cyanide. Cillian Murphy in ‘Oppenheimer' (Melinda Sue Gordon ...
The M44 cyanide device (also called a cyanide gun, cyanide trap, or canid pest ejector) is used to kill coyotes, feral dogs, and foxes. It is made from four parts: a capsule holder wrapped with cloth or other soft material, a small plastic capsule containing 0.88 grams of sodium cyanide , a spring-powered ejector, and a 5–7 inches (130–180 ...

[3] Reaction of the sodium cyanoacetate with ethyl bromide in an aqueous–organic two-phase system in the presence of a phase transfer catalyst. [4] Oxidation of 3-ethoxypropionitrile, an ether, with oxygen under pressure in the ...
2OC(NH 2) 2 + Na 2 CO 3 → 2Na(NCO) + CO 2 + 2NH 3 + H 2 O. Sodium allophanate is observed as an intermediate: [2] H 2 NC(O)NHCO 2 Na → NaOCN + NH 3 + CO 2. It can also be prepared in the laboratory by oxidation of a cyanide in aqueous solution by a mild oxidizing agent such as lead oxide. [3]
