Sodium Nitrite 500gm

Uses of Sodium Nitrite

Analytical Chemistry:

Sodium nitrite is used as a reagent in the qualitative and quantitative analysis of certain compounds. It’s involved in the diazotization reaction, which is essential in the detection of amines.

Synthesis:

It’s a key intermediate in the synthesis of various organic compounds, including pharmaceuticals, dyes, and agrochemicals. Sodium nitrite is used in the preparation of diazonium salts, which are important intermediates in organic synthesis.

Corrosion Inhibition:

In studies related to corrosion, sodium nitrite is used to inhibit the corrosion of metals. It acts as an anodic inhibitor, forming a protective oxide layer on the surface of the metal.

Preservation of Biological Samples:

Sodium nitrite is used to preserve biological samples, such as tissues, by preventing bacterial growth and decomposition.

Nitrosation Reactions:

It is used in nitrosation reactions, which involve the introduction of a nitroso group (–NO) into an organic molecule. This reaction is significant in the study of nitrosamines and their effects.

Redox Reactions:

Sodium nitrite is involved in various redox reactions. It can act as both an oxidizing and a reducing agent, depending on the reaction conditions.

Cyanide Poisoning Antidote:

In toxicology studies, sodium nitrite is used as an antidote for cyanide poisoning. It works by inducing the formation of methemoglobin, which binds to cyanide and helps detoxify it.
