Electric Literature of 63572-73-6, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 63572-73-6, name is 5-Nitro-1H-pyrazolo[3,4-b]pyridine. This compound has unique chemical properties. The synthetic route is as follows.
5-Nitro–1H-pyrazolo[3,4-b]pyridine (prepared according to the procedure in Can. J. Chem. 1988, 66(3), 420) (133 mg, 0.81 mmol) was mixed with SnCI2 (1.0g) in EtOH/CH3Ph (4 mL/2mL) and heated at 70 0C for 3 hrs. The reaction was cooled to rt and concentrated to dryness. The residue was participated between 1.0 N NaOH (10 mL) and ethyl acetate (50 mL). The organic layer was washed with brine once, dried (MgSO4) and filtered. The filtrate was concentrated and the resulting crude was purified by prep. TLC using 10:2 CH2CI2/Methanol(2 N NH3). The title compound (15.0 mg) was isolated as a yellow solid.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 63572-73-6, 5-Nitro-1H-pyrazolo[3,4-b]pyridine.
