Detailed Product Description:
A colorless, odorless, crystalline powder. Saline, slightly
bitter taste. Soluble in water and glycerol. Slightly soluble
Sodium nitrite is used as a color fixative and preservative in
meats and fish. When pure, it is a white to slight yellowish
crystalline powder. It is very soluble in water and is hygroscopic.
It is slowly oxidized with exposure to air to sodium nitrate,
NaNO3. It is a strong reducing agent.
This is Reagent-Grade material with a minimum purity of 99.0%
Sodium Nitrite is used in manufacturing diazo dyes, nitroso compounds,
and other organic compounds; in dyeing and printing textile fabrics
and bleaching fibers; in photography; as a laboratory reagent and a
corrosion inhibitor; in metal coatings for phosphatizing and de-tinning;
and in the manufacture of rubber chemicals. Sodium nitrite also has
been used in human and veterinary medicine as a vasodilator, a
bronchodilator, an intestinal relaxant or a laxative, and an antidote
for cyanide poisoning.
As a food additive, Sodium Nitrite serves a dual purpose in the food
industry, altering the color of preserved fish and meats and preventing
growth of Clostridium botulinum, the bacteria which causes botulism.
While this chemical will prevent the growth of bacteria, it can be toxic
for mammals (LD50 in rats is 180 mg/kg). For this reason, sodium
nitrite sold as a food additive is dyed bright pink to avoid mistaking
it for something else. Cooks and makers of charcuterie often simply
refer to sodium nitrite as "pink salt".
Various dangers of using this as a food additive have been suggested
and researched by scientists. A principal concern is the formation of
carcinogenic N-nitrosamines by the reaction of sodium nitrite with
amino acids in the presence of heat in an acidic environment.
Sodium nitrite is also used to convert amines into diazo compounds. The
synthetic utility of such a reaction is to render the amino group labile for
nucleophilic substitution, as the N2 group is a better leaving group. In
the laboratory, sodium nitrite is also used to destroy excess sodium azide.
Strong oxidizer. Can cause fire in contact with organic materials.
