In chemistry, cyanide (from Greek kyanos ' dark blue ') is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. [1] In inorganic cyanides, the cyanide group is present as the cyanide anion −C≡N.
The evidence for sodium thiosulfate's use is based on animal studies and case reports: the small quantities of cyanide present in dietary sources and in cigarette smoke are normally metabolized to relatively harmless thiocyanate by the mitochondrial enzyme rhodanese (thiosulfate cyanide sulfurtransferase), which uses thiosulfate as a substrate. However, this reaction occurs too slowly in the ...
Jun 21, 2024 · cyanide, any compound containing the monovalent combining group CN. In inorganic cyanides, such as sodium cyanide (NaCN), this group is present as the negatively charged cyanide ion; these compounds, which are regarded as salts of hydrocyanic acid, are highly toxic. Organic cyanides are usually called nitriles; in these, the CN group is linked ...

Nov 18, 2019 · Respiratory failure. Coma. Death from poisoning usually results from respiratory or heart failure. A person exposed to cyanide may have cherry-red skin from high oxygen levels or dark or blue coloring, from Prussian blue (iron-binding to the cyanide ion). Also, skin and body fluids may give off an odor of almonds.

Cyanide is a dangerous chemical that can cause serious health problems or death if exposed. Learn how to recognize the signs and symptoms of cyanide poisoning, how to decontaminate yourself and others, and how to seek medical treatment. This webpage provides basic facts and guidance for chemical emergencies involving cyanide.
Management of cyanide toxicity is based on the principle of reversing and/or displacing cyanide binding to cytochrome a3. There are two major modalities of treatment: hydroxocobalamin and . the cyanide antidote kit containing sodium nitrate and sodium thiosulfate. 5 • Hydroxocobalamin (Cyanokit): The preferred antidote, based on a 2018 US ...
