Sodium nitrite, 1 X 2.5 kg (S2252-2.5KG)

Sodium nitrite is an air-sensitive and hygroscopic solid with both reducing and oxidizing properties. It is commonly used as a reagent and catalyst in synthetic organic chemistry. It is decomposed by acids (even weak acids) with the evolution of a brown mixture of nitrogen oxides (NOₓ). Sodium nitrite can be used as a reagent in:       •In the conversion of amines into diazo compounds, which are used as key precursors to many dyes, such as diazo dyes.       •Nef reaction and Abidi transformations.       •The C–C bond cleavage reaction in the presence of TFA under aerobic conditions.       •The oxidative carbonitration of alkenes in the presence of K₂S₂O₈. It can also be used as a nitrating agent in organic synthesis. It is used in direct C-H nitration, ipso-nitration, and nitration via transition metal-catalyzed cross-coupling reaction. NaNO₂ is also used as a co-catalyst for catalytic oxidation of alcohols under aerobic, solvent-free conditions.
