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.
