SODIUM NITRITE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Nitrite is a white, crystalline inorganic compound with the chemical formula NaNO2. It is used in various industrial, chemical, and food applications as a preservative, antioxidant, and curing agent. In the food industry, Sodium Nitrite is commonly used in the curing of meats, providing color, flavor, and antimicrobial properties to processed meats such as bacon, ham, and sausages. It is also employed in the production of certain dyes and pharmaceuticals, where it acts as a reagent and intermediate. In the chemical industry, Sodium Nitrite is used as a corrosion inhibitor and as a reagent in the synthesis of various organic compounds. Proper handling and storage of Sodium Nitrite are essential to maintain its quality and prevent moisture absorption. It is generally considered safe for use in regulated amounts, although proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential to prevent irritation and other health hazards. Its versatility and effectiveness make Sodium Nitrite a valuable chemical in numerous applications.
