5-Nitro-3-pyrazolecarboxylic acid Chemical Properties,Usage,Production

Chemical Properties

off-white to light yellow crystalline powder

Uses

5-Nitro-1H-pyrazole-3-carboxylic acid was investigated for potential therapeutic properties on ocular blood flow and retinal function recovery after reperfusion injury and ischemic insult.

Synthesis

3-Methyl-5-nitrothiazole (0.18 mol) was dissolved in concentrated H2SO4 (300 mL) and Na2Cr2O7-2H2O (53 ) was added to the mixture. g, 0.27 mol) was added dropwise to this solution and the temperature was maintained at 60-65??C. The reaction mixture was kept at this temperature for 8 h. The reaction mixture was poured into ice (1 kg) and extracted with ethyl acetate (3 x 250 mL). The organic layer was washed with water, dried with MgSO4, the solvent was removed in vacuo and the residue was recrystallized from H2O to give 3-nitropyrazole-5-carboxylic acid in a yield of 25 g (88%).
