Infobox references

Benzoylhydrazine, also known as benzenecarbohydrazide, or benzoic hydrazide is an organic chemical compound, which is a hydrazide functionally linked to benzoic acid. It is typically used as a precursor in pharmaceutical and chemical synthesis, or used as a chemical intermediate for the production of hydrazine-based products.

Metabolism

During metabolism it forms metabolites including hydrazine, benzoic acid and hippuric acid.[1][2]

Safety

It is both neurotoxic and hepatoxic as well as an osteolathyrogen and carcinogen, and also a potential teratogen that affects the development of fetal abnormalities.[3][4][5][6][7][8][9][10]

The mechanism responsible for the development of osteolathyrism is identical to the reference osteolathyrogen β-aminopropionitrile.[8][7][9]

A violent reaction occurs with benzeneselenic acid. When heated to decomposition it emits toxic fumes of nitrogen oxides.[11][1]
