271° dec.
Storage & Sensitivity
Hygroscopic. Ambient temperatures.
Soluble in water, methanol, ethanol, ammonia, nitric acid. Slightly soluble diethyl ether.


Sodium nitrite is used in many industrial applications viz. in meat curing, coloring and preserving. It is used as a reagent in analytical chemistry, an antidote in cyanide poisoning, an electrolyte in electrochemical grinding, as a cooling solution in closed loop systems and as an additive in industrial greases. It finds application as a corrosion inhibitor as well as in the rubber industry. In metallurgy, it is used for phosphatizing and detinning. It acts as a precursor to diazo dyes, nitroso compounds and various organic compounds like pharmaceuticals. As a food additive, it is used to prevent botulism.


Decomposes above 320°. Hygroscopic. Incompatible with reducing agents, strong oxidizing agents, organics, finely powdered metals.
