Product Application Of Phenylhydrazine CAS#100-63-0
As the first synthetic hydrazine derivative phenylhydrazine serves widely as an intermediate in organic dyes pharmaceuticals and pesticides. It is a key building block for synthesizing pyrazoline triazole and indole compounds. It acts as a dye intermediate for products like 1-phenyl-3-methyl-5-pyrazolone used in disazo dyes. In pharma it supports the production of antipyretics analgesics and anti-inflammatory agents such as antipyrine and aminopyrine. It also functions as a photosensitive dye in photography and is a raw material for the pesticide imputed phosphorus. Additionally it is a classic reagent for detecting carbonyl groups aldehydes ketones and carbohydrates.
Phenylhydrazine is highly toxic Inhalation can lead to hemolysis anemia headaches and severe cases may involve jaundice It irritates the eyes and may cause corneal damage The oral LD50 in rats is 188 mg/kg The maximum allowed concentration at workplaces is 0.44mg/m3
In laboratory synthesis aniline reacts with sodium nitrite in hydrochloric acid to form a diazonium salt This intermediate is reduced with sulfur dioxide and sulfurous acid to phenylhydrazine sodium sulfonate Further treatment with hydrochloric acid yields phenylhydrazine hydrochloride Neutralization and deacidification produce the final phenylhydrazine product.
