4-NITROBENZHYDRAZIDE Usage And Synthesis

Synthesis

Dissolve 218 g of p-nitrobenzyl acetate in 500 ml of hot methanol, stir, and slowly add 380 g of 15% sodium hydroxide solution. After the addition was completed, it was placed for 5 minutes, and then poured into ice water to precipitate a precipitate. The filtered precipitate was decolorized with activated carbon in hot water, and recrystallized to give p-nitrobenzoicacidhydrazide 110-121 g .

Chemical Properties

yellow crystalline powder

Uses

4-Nitrobenzoic hydrazide has been used as internal standard in determination of isoniazid in human plasma by LC-MS/MS method.

Definition

ChEBI: A C-nitro compound in which the nitro group is substituted into the 4-position of benzohydrazide.
