Phenylhydrazine is used to prepare indoles by the Fischer indole synthesis, which are intermediates in the synthesis of various dyes and pharmaceuticals. Phenylhydrazine is used to form phenylhydrazones of natural mixtures of simple sugars in order to render the differing sugars easily separable from each other. … Zobraziť viac Phenylhydrazine is the chemical compound with the formula C6H5NHNH2. It is often abbreviated as PhNHNH2. It is also found in edible mushrooms. Zobraziť viac Phenylhydrazine is prepared by oxidizing aniline with sodium nitrite in the presence of hydrogen chloride to form the diazonium salt, which is subsequently reduced using sodium sulfite in the presence of sodium hydroxide to form the final product.
