Product Application of Phenylhydrazine CAS#100-63-0

In the field of pesticide production, phenylhydrazine can be used for synthesizing the intermediate 1-phenyl-semicarbazide of the organophosphorus pesticides, triazophos as well as the intermediate 1-phenyl-3, 6-hydroxy pyridazine of pyridaphenthione. It is also the intermediates of the novel bactericidal varieties, famoxadone and fenamidone. In addition, hydrazine benzene, as a raw material for organic synthesis, can also be used as the intermediates of dye and pharmaceutical industry as well as being used as an analytical reagent.
The product is the intermediate of dye, pharmaceuticals and pesticides. It can be used for the production of Naphthol AS-G, drugs such as antipyrine and so on. Dissolving the phenylhydrazine in 95% ethanol and following by addition of benzaldehyde and reflux for 1 h can obtain the phenylhydrazone. Phenylhydrazone can also be used as the intermediate of organic synthesis. Phenylhydrazine is also used as an analytical reagent.
As a weak base, it can be used to precipitate lead, chromium and other trivalent, tetravalent element in the form of hydroxide. It can also be used for photometric determination of aluminum, chromium, copper, molybdenum, titanium, and zirconium. It can also be used for verification of gold, iridium, molybdenum, palladium, platinum, and silver. It can be used as the reducing agent for colorimetric assay of phosphorus acid. It can also react with aldehydes, ketones and sugars to get phenylhydrazone with different melting points according which we will be able to identify these substances.
