Sodium hydrazide is an inorganic compound with the formula NaN2H3. It is a pale yellow solid that detonates when in contact withair,water, oralcohol.[1]
Sodium hydrazide was first observed as a mixture withsodium hydroxide in 1895 when excesssodium metal was added to hydrazine hydrate under nitrogen.[5] Subsequently, sodium hydrazide was isolated in pure form byWilhelm Schlenk in 1915 by the reaction of sodium metal and anhydroushydrazine, followed by removal of the excess hydrazine by heating to 60 °C:[1][2]
It can also be produced by the reaction ofsodium amide orsodium hydride and hydrazine.[6]
Sodium hydrazide is a pale-yellow solid that detonates when heated above 100 °C.[4] It also detonates when in contact with air, water, or alcohol, such asethanol.[2][7] Due to this, it is used as a suspension inbenzene ordiethyl ether in organic reactions. It is capable of doing nucleophilic additions to various compounds, such asnitriles, which are converted toamidrazones.[4][3]
