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.
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.
It is a key reagent in the industrial production of organonitrogen compounds, such as those used in pesticides and other organic compounds.
It has applications in metal treatment processes, such as phosphatizing and detinning.
It is used as an additive in industrial greases and as an aqueous solution in cooling systems to prevent corrosion.
It can be used in a molten state as a heat transfer medium.
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.
It is an oxidizer and should be kept away from combustible materials and sources of heat.
