As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 100-48-1, name is Isonicotinonitrile, molecular formula is C6H4N2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Safety of Isonicotinonitrile
(d) 4-Pyridinecarboxamidine hydrochloride A solution of 4-pyridinecarbonitrile (370 g, 3.55 mol) and sodium methoxide (20.0 g, 0.37 mol) in methanol (1.71) was stirred at room temperature for 1.5 hours, then ammonium chloride (200 g, 3.7 mol) was added. The reaction mixture was stirred for 24 hours, the resulting solid was collected by filtration and the filtrate was evaporated to dryness. The two crops were combined and recrystallized from water to afford 394 g (70percent) of 4-pyridinecarboxamidine hydrochloride, m.p. 250°-252° C. (dec.).
With the rapid development of chemical substances, we look forward to future research findings about 100-48-1.
