Synthetic Route of 89501-90-6<\/a>, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 89501-90-6 as follows.<\/p>\n

EXAMPLE 5 1-Methylpyrazole-3-sulfonamide A mixture containing chloroform (100 ml), 13.6 g of 1-methylpyrazole-3-sulfonyl chloride and 13.6 g ammonium carbonate was heated to reflux for six hours, cooled, filtered and the solid was washed with water. The water-insoluble solid which was recrystallized from 50% ethanol-water melted at 149-151 and showed absorption peaks in the infrared at 3100 and 3200 cm-1, consistent for the NH2 in the desired product. Anal. Calc. for C4 H7 N3 O2 S: C, 29.8; H, 4.38; N, 26.07; S, 19.9. Found: C, 29.3; H, 4.6; N, 25.3; S, 19.2.<\/p>\n

According to the analysis of related databases, 89501-90-6, the application of this compound in the production field has become more and more popular.<\/p>\n
