Sodium Nitrite, 200 grams
Price:
$48.95
Chemical Name:
Sodium Nitrite
CAS Number:
7632-00-0
Chemical Formula:
NaNO2

Detailed Product Description:

A colorless, odorless, crystalline powder.  Saline, slightly

bitter taste.  Soluble in water and glycerol.  Slightly soluble

in alcohol.

 

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.

 

Grade/Purity:

This is Reagent-Grade material with a minimum purity of 99.0%

 

Applications:

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.

 

Precautions:

Strong oxidizer.  Can cause fire in contact with organic materials.
