NaNO2 i.e. sodium nitrite, is an inorganic salt of Inorganic Chemicals, yellowish-white solid, soluble, formed (1) by reaction of nitric Oxide plus nitrogen dioxide and sodium carbonate or hydroxide, and then evaporating, (2) by heating sodium nitrate then lead to a high temperature, and then extracting the soluble portion (lead monoxide insoluble) with H2O and evaporating. It is used as an important reagent (diazotizing) in the Organic Chemistry. Wuhan Ruisunny Chemical Co., Ltd has been trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide, Hydrogen Peroxide and Silane etc. since 2007, as to this product, we have following as:

Safety Profile
Noncombustible but will accelerate the burning of combustible material. If large quantities are involved in a fire or if the combustible material is finely divided, an explosion may result. If contaminated by ammonium compounds, spontaneous decomposition can occur and the resulting heat may ignite surrounding combustible material. Prolonged exposure heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving Sodium nitrite.
4) Application:
Sodium nitrite is used as an intermediate for dye stuffs and for pickling of meat, in dyeing of textiles, in rustproofing, in medicine, and as a reagent in organic chemistry.
