Application of 147619-40-7, 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 147619-40-7, name is 5-Chloro-4-methoxy-2-oxo-1,2-dihydropyridine-3-carbonitrile. This compound has unique chemical properties. The synthetic route is as follows.
Add in 250ml three-necked flask5-chloro-4-methoxy-3-cyano-2- (1H) pyridone,48percent hydrobromic acid 150 ml,Heating reflux reaction for about 20-24 hours,Stop the reaction, this time the system is dark red solution.The reaction solution was concentrated at 90-95 ° C under reduced pressure to dryness,Add 200ml purified water beating,After stirring for 1 hour, the filtrate was filtered.Filter cake in 55-60 blast drying,Brown solid,That gimeracil,Weight 6.57 g, yield 83.2percentPurity of 99.91percent (see Figure 1),
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 147619-40-7, 5-Chloro-4-methoxy-2-oxo-1,2-dihydropyridine-3-carbonitrile.
