Hydrogen Cyanide: Acute Exposure Guideline Levels

Hydrogen cyanide (HCN) is a colorless, rapidly acting, highly poisonous gas or liquid that has an odor of bitter almonds. Most HCN is used as an intermediate at the site of production. Major uses include the manufacture of nylons, plastics, and fumigants. Exposures to HCN may occur in industrial situations as well as from cigarette smoke, combustion products, …

Waterstofcyanide

Waterstofcyanide of blauwzuur is een anorganische verbinding van waterstof, koolstof en stikstof, met als brutoformule HCN. Het is een extreem giftige kleurloze tot zeer licht blauwe vloeistof, die vlak boven kamertemperatuur kookt. Het is een zwak zuur en het is goed oplosbaar in water. ...

Hyperpolarization-activated cyclic nucleotide gated (HCN) channels and the current they carry, Ih, are widely and diversely distributed in the central nervous system (CNS). The distribution of the four subunits of HCN channels is variable within the CNS, within brain regions, and often within subcellular compartments.

Cyjanowodór – Wikipedia, wolna encyklopedia

Cyjanowodór, HCN – nieorganiczny związek chemiczny zbudowany z wodoru, węgla i azotu, będący bezbarwną, lotną i silnie trującą cieczą o zapachu gorzkich migdałów (który może być jednak niewyczuwalny dla niektórych osób). Z wodą tworzy słaby kwas cyjanowodorowy (kwas pruski), którego sole noszą nazwę cyjanków.

The Addition of Hydrogen Cyanide to Aldehydes and Ketones

The mechanism for the addition of HCN to propanone In the first stage, there is a nucleophilic attack by the cyanide ion on the slightly positive carbon atom. The negative ion formed then picks up a hydrogen ion from somewhere - for example, from a hydrogen cyanide molecule.
