Sodium Nitrite AR 500g
While it is also used as a food preservative and as an antidote for cyanide poisoning, these specific uses would involve different grades and handling procedures than the “AR” (analytical reagent) grade, which is designed for laboratory-scale work.
-
Synthesis of dyes and pigments:
AR-grade sodium nitrite is used in the laboratory to convert amines into diazo compounds, which are precursors for many dyes, pigments, and printing inks.
-
Production of other chemicals:
It is a key reagent in the industrial production of organonitrogen compounds, such as those used in pesticides and other organic compounds.
-
Metal treatment:
It has applications in metal treatment processes, such as phosphatizing and detinning.
-
Corrosion inhibitor:
It is used as an additive in industrial greases and as an aqueous solution in cooling systems to prevent corrosion.
-
Heat transfer:
It can be used in a molten state as a heat transfer medium.
- Food preservative: It is a common food preservative and color fixative in cured meats, fish, and cheeses.
- Medical antidote: It is a critical component in the antidote for cyanide poisoning.
-
Handling:
AR-grade sodium nitrite is a hazardous substance. It is toxic if swallowed, and handling should be done with appropriate personal protective equipment, such as gloves, eye protection, and respiratory protection.
-
Flammability:
It is an oxidizer and should be kept away from combustible materials and sources of heat.
-
Environment:It is very toxic to aquatic life and should be prevented from entering the environment.Sodium Nitrite AR 500g
