Second, the Synthetic Route we will recommend is the most important for your reference?

First, synthesis line of 4-Nitrophenylhydrazine CAS NO.100-16-3 as follows

Main production methods:

Dissolve p-nitroaniline in hydrochloric acid, cool to 0 ℃, add sodium nitrite solution for diazotization, and filter. Add the filtrate to a cooled mixture of sodium sulfite and sodium hydroxide, then add concentrated hydrochloric acid to make it acidic. Warm it at 25 ℃ for half an hour and filter to obtain p-nitrophenylhydrazine hydrochloride. Dissolve in water and add sodium acetate deep solution to precipitate p-nitrophenylhydrazine with a yield of 63-72%.
