Phenylhydrazine is used in pesticide production to synthesize the intermediates of organophosphorus insecticide triazophos, 1-phenylaminocarbamide and pyridazinophos, 1-phenyl-3,6-dihydroxy pyridazine. It is also used as the intermediates of new fungicides, Famoxadone and fenamidone. In addition, phenylhydrazine is used as an organic synthetic raw material and also as an organic synthetic material. Intermediates in dyes, pharmaceuticals and other industries are also used as analytical reagents.
It can react with aldehydes and ketones of sugars to form stable sugar anthracene (sa, four tones). Different reducing sugars can be identified by the crystal form and melting point of sugar anthracene.
