3-Methyl-6-nitroindazole Chemical Properties,Usage,Production
Description
3-Methyl-6-nitroindazole is an important organic reagent or pharmaceutical intermediate compound used in the preparation of key intermediates of pazopanib. In experimental studies, it is mostly used for solubility determination, correlation and molecular interaction analysis studies in different pure and mixed solvents. The results showed that in the temperature range of (278.15 ~ 328.15)K, the molar fraction solubility of 3-Methyl-6-nitroindazole increased with increasing temperature in both pure and mixed solvent systems, and was maximum in pure N, N-dimethylformamide and minimum in water.
Chemical Properties
Brown solid
Uses
3-Methyl-6-nitroindazole a reactant used in the preparation of Pazopanib (P210925), an oral angiogenesis inhibitor targeting VEGFR and PDGFR.

Physical properties
3-Methyl-6-nitroindazole, a slightly yellow to tawny powder with a molecular weight of 177.16, is one critical intermediate of Pazopanib. The chemical structure of 3-methyl-6-nitroindazole is shown below. Wang et al. measured the solubility of 3-methyl-6-nitroindazole in eight pure solvents [i.e., N, N-dimethylformamide (DMF), tetrahydrofuran (THF), acetone, ethyl acetate (EA), ethanol, acetonitrile, n-propanol, water] and three mixed solvents (DMF + water, THF + cyclohexane, acetone + water) at temperatures T = 278.15 to 328.15 K and under atmosphere pressure. Whether in a pure solvent or a mixed system, the results show that mole fraction solubilities of 3-methyl-6-nitroindazole increased with increasing temperature. Among the three groups of mixed solvents measured, the molar fraction of 3-methyl-6-nitroindazole in the (DMF + water) system is the maximum[1-2].
