Common NameSodium nitrite
DescriptionNitrous acid, also known as NANO2 or natrium nitrit, belongs to the class of inorganic compounds known as alkali metal nitrites. These are inorganic compounds in which the largest oxoanion is nitrite, and in which the heaviest atom not in an oxoanion is an alkali metal. Nitrous acid is a drug which is used for sequential use with sodium thiosulfate for the treatment of acute cyanide poisoning that is judged to be life-threatening [fda label]. Nitrite poisoning causes methemoglobinemia. Nitrite can be oxidized to nitrate by oxyhemoglobin. Nitrous acid is an extremely weak basic (essentially neutral) compound (based on its pKa). In humans, nitrous acid is involved in nitric oxide signaling pathway. Sodium nitrite may also be used in organic synthesis, in dyeing and printing textile fabrics, in photography, as a laboratory reagent and a corrosion inhibitor, and in the manufacture of rubber chemicals. Outside of the human body, Nitrous acid has been detected, but not quantified in, fishes. This could make nitrous acid a potential biomarker for the consumption of these foods. It was first documented in 2014 (PMID: 24200576). Nitrous acid is a potentially toxic compound (PMID: 24266433) (PMID: 24333935) (PMID: 24363302) (PMID: 24535441).
