The CAS number of Sodium nitrite is 7632-00-0.
Sodium nitrite is an inorganic compound with the chemical formula NaNO2. It is an odorless, white to yellowish, crystalline powder that is soluble in water and is commonly used as a food preservative and a color fixative. Sodium nitrite is also used in many industrial applications, such as in the production of dyes, pigments, and rubber chemicals.
One of the primary uses of sodium nitrite is as a food preservative. It is added to processed meats such as bacon, ham, and sausage to prevent the growth of harmful bacteria and to ensure the product remains fresh for a longer period of time. Sodium nitrite is also used as a color fixative in cured meats, giving them the characteristic pink color that consumers associate with them.
Sodium nitrite has other uses in the food industry as well. It is used as a food coloring agent in some products, such as smoked fish and cheese. It is also used in the production of pickles and other canned vegetables to prevent spoilage.
While sodium nitrite is primarily used in the food industry, it is also used in other applications. For example, it is used in the production of explosives and as a corrosion inhibitor in some industrial processes. Sodium nitrite is also used as a reducing agent in some chemical reactions.
Despite its many uses, sodium nitrite has some potential health concerns. Consumption of high levels of sodium nitrite has been linked to an increased risk of some types of cancer. However, the amounts of sodium nitrite used in food products are generally well below the level that poses a significant risk.
Overall, sodium nitrite is a useful and important chemical that has many uses in our daily lives. While it is important to be aware of its potential health risks, the proper use of sodium nitrite in food products and other applications can help ensure its continued safe use.
