Descrição

Descrição geral

Hydrazine monohydrobromide (hydrazinium bromide) is a hydrobromide salt of hydrazine. It has been prepared by adding aqueous hydrobromic acid to aqueous hydrazine.[1] Its crystal structure has been investigated.[2] It participates in the synthesis of 2-(2′-furoyl)-4(5)-(2′-furanyl)-1H-imidazole (FFI).[3] It is formed as an intermediate during the formation of phosphaminimides from hydrazide derivatives.[4] The fumes from the pyrolysis of hydrazine monohydrobromide soldering flux have been reported to cause dermatitis.[5]

Aplicação

Hydrazine monohydrobromide (hydrazinium bromide) may be used in the synthesis of bromostannates and bromostannites by reacting with tin bromide[6] and also in soldering flux.[5]
