In the past, sodium nitrate was used to help preserve and enhance the flavor profile of meats. [19] It is generally agreed upon that sodium nitrite is not considered effective for controlling gram-negative enteric pathogens such as Salmonella and Escherichia coli. Clean Air Act: This material does not contain any hazardous air pollutants. Sodium nitrite is sold as the salt and in solution. [3], Sodium nitrite is an effective corrosion inhibitor and is used as an additive in industrial greases,[4] as an aqueous solution in closed loop cooling systems, and in a molten state as a heat transfer medium. Sodium nitrate is a food additive that is used to add flavor and color and to prolong the shelf life of food. System Generated Number.

[19], Sodium nitrite is toxic. Sodium nitrite is an inorganic compound with the chemical formula NaNO2. N-O2.Na. It is only recommended in severe cases of cyanide poisoning. [19] Lipid peroxidation is considered to be a major reason for the deterioration of quality of meat products (rancidity and unappetizing flavors). infrared reference spectra collection. [8], Sodium nitrite consumption has also been linked to the triggering of migraines in individuals who already suffer from them. It is on the World Health Organization's List of Essential Medicines, a list of the most important medications needed in a basic health system. The finely crystalline, slightly yellowish salt is marketed in untreated form and also after treatment with aryl alkyl sulfonates. [39] Nitric oxide can be created de novo from nitric oxide synthase utilizing arginine or from ingested nitrate or nitrite. This material contains Sodium nitrite (CAS# 7632-00-0, >97%),which is subject to the reporting requirements of Section 313 of SARA Title III and 40 CFR Part 373. Sodium nitrite is currently used in the medical treatment of cyanide poisoning and has public health use as a curing agent. [13] Sodium nitrite is responsible for the desirable red color (or shaded pink) of meat. The World Health Organization's review of more than 400 studies concluded, in 2015, that there was that there was sufficient evidence that "processed meats" caused cancer, particularly colon cancer; the WHO's International Agency for Research on Cancer (IARC) classified "processed meats" as carcinogenic to humans (Group 1); "processed meat" meaning meat that has been transformed through salting, curing, fermentation, smoking, or other processes to enhance flavour or improve preservation.). Moreover, the crystal structure of sodium nitrite is orthorhombic. 11 Product Results ... UV-VIS Standard 2: Sodium nitrite solution.

It has a white-yellowish crystalline appearance. [19], A 2018 study by the British Meat Producers Association determined that legally permitted levels of nitrite have no effect on the growth of the Clostridium botulinum bacteria which causes botulism, in line with the UK’s Advisory Committee on the Microbiological Safety of Food opinion that nitrites are not required to prevent C. botulinum growth and extend shelf life. [8][46], Nitrosamines can be formed during the curing process used to preserve meats, when sodium nitrite-treated meat is cooked, and also from the reaction of nitrite with secondary amines under acidic conditions (such as occurs in the human stomach). The structural formula is: Structure of Sodium Nitrite. EC Number 231-555-9. For the use of sodium nitrite as a medication, see, "E250" redirects here.

[20] In some countries, cured-meat products are manufactured without nitrate or nitrite, and without nitrite from vegetable source. [8][9] Nitrite reacts with the meat myoglobin to cause color changes, first converting to nitrosomyoglobin (bright red), then, on heating, to nitrosohemochrome (a pink pigment). Emergency Overview Oxidizer: Contact with combustible/organic material may cause fire. H-N-O2.Na. Sodium Nitrite Injection is a sterile aqueous solution and is intended for intravenous injection. click the mouse on the plot to revert to the orginal display. The nitrite ion has a symmetrical structure (C 2v symmetry), with both N–O bonds having equal length and a bond angle of about 115°.
