Application of 29939-37-5, 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 29939-37-5 as follows.
A mixture comprising 5.0 g (39.6 mmol) 6-hydrazinopyrimidin-4-ol/6-hydrazinopyrimidin- 4(1 H)-one (CAS-No: 29939-37-5), 5.12 g pentan-3-one and 80.8 mL ethanol was heated under reflux for 2 hours. After cooling to 3C, the precipitated solid was filtered off and washed with diethyl ether to give 5.82 g (72%) of the title compound
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,29939-37-5, its application will become more common.
