Sodium Nitrite AR 500g

Sodium Nitrite AR 500g

Sodium nitrite (AR grade) is primarily used in laboratories for chemical synthesis as a reagent to create compounds like dyes and pesticides. It is also used in industrial applications such as metal treatment and as a corrosion inhibitor.

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.

Sodium Nitrite AR 500g Chemical and industrial uses

• 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.

Other uses

• 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.

Important safety note

• 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
