3-methyl-6-oxo-1-phenyl-1H-dihydro-1H-pyrazolo - (2-pyridine-5-carbonitrile)52217-38-6 98% g/kg
Chinese name 1H-Pyrazolo [3,4-b] pyridine-5-carbonitrile, 6,7-dihydro-3-methyl-6-oxo-1-phenyl - Chinese synonym 6,7-dihydro-3-methyl-6-oxo-1-phenyl-1H-pyrazolo [3,4-B] pyridine-5-3-methyl-6-oxo-1-phenyl-6,7-dihydro-1H-pyrazolo [3,4-B] pyridine-5-carbonitrile; Pyrazole pyridine derivatives 3,4-b] pyridine-5-carbonitrile; 3-methyl-6-oxo-1-phenyl-7H-pyrazole [3,4-b] pyridine-5-carbonitrile has a melting point of 306-308 ° C (Solv: acetic acid), a boiling point of 504.8 ± 50.0 ° C (Predicted), a density of 1.34 ± 0.1g/cm3 (Predicted), and an acidity coefficient (pKa) of 9.68 ± 0.40 (Predicted). 3-Chloropropyl acetate is a carboxylic acid derivative that can be used as an organic synthesis intermediate in the production of dyes. Chemical properties: Colorless liquid. Boiling point 163-165 ℃ (99.6kPa), 80-81 ℃ (4.0kPa), 62-62 ℃ (1.33kPa), relative density 1.250Chemicalbook (19/4 ℃), refractive index 1.431. Soluble in ethanol, acetone, insoluble in water. Application: Organic synthesis intermediate, used in the production of dyes. The production method is obtained by reacting propanol with acetyl chloride. Slowly add acetyl chloride to propanol, heat and reflux until no more hydrogen chloride is released, and distill to obtain the finished product with a yield of 86%.
