504-17-6, 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. 504-17-6, name is 4,6-Dihydroxy-2-mercaptopyrimidine, molecular formula is C4H4N2O2S, 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.

General procedure: A mixture of an aldehyde (0.25 mmol), 2-thiobarbituric acid (0.5 mmol), ammonium acetate (0.3 mmol), and CuFe2O4 (10 mol%), with distilled H2O, in an open tall beaker was irradiated inside microwave oven at 100 W for an appropriate time (monitored by TLC). After completion of the reaction, for removing the catalyst, the hot solution was filtrated with external magnetic for several times. The solvent was evaporated, and the precipitate was washed from ethanol and hot water to afford the pure product.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 504-17-6, 4,6-Dihydroxy-2-mercaptopyrimidine, other downstream synthetic routes, hurry up and to see.

A common compound: 504-17-6, name is 4,6-Dihydroxy-2-mercaptopyrimidine,molecular formula is C4H4N2O2S, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below., 504-17-6

General procedure: To a mixture of an aromatic aldehyde (0.25 mmol), 2-thiobarbituric acid(0.5 mmol), ammonium acetate (0.3 mmol), [H-NMP]+[HSO4]- (12 mol%)and water (2 ml) was added. Then, ultrasonic probe was directly immersed inthe resulting mixture. The progress of the reactions was monitored by TLCuntil conversion of the starting materials was satisfactory. After completion ofthe reaction, the solvent was evaporated and the precipitate was washed withEtOH and hot water to afford the pure product. All products were identified byphysical and spectroscopic data. The synthesis of the compounds 4b and 4j wasinvestigated but unfortunately even after 24 h, only a trace amount of productwas observed by TLC, that is why we could not reported the spectroscopic dataof them.

With the rapid development of chemical substances, we look forward to future research findings about 504-17-6.

Here is a downstream synthesis route of the compound, 504-17-6, blongs to pyrimidines compound.

General procedure: [H2-DABCO][H2PO4]2 (0.065mmol, 0.020 g) was added to a mixture of the aromatic aldehyde (1 mmol), malononitrile (1 mmol) and barbituric or thiobarbituric acid (1 mmol) in water (3 mL). Then the mixture was heated at 75 C while was monitored by TLC (n-hexane:ethyl acetate; 1:9). After completion of the reaction, the mixture was cooled to room temperature and the solid productwas filtered, washed with cold distilled water (2 mL) and was recrystallized from warm ethanol if necessary.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,504-17-6, its application will become more common.

Some common heterocyclic compound, 504-17-6, molecular formula is C4H4N2O2S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.504-17-6

General procedure: Nano-sawdust-OSO3H (0.02 g) was added to a stirred mixture of the aromatic aldehyde (1 mmol), malononitrile (1 mmol) and barbituric acid or thiobarbituric acid (1 mmol) in EtOH (5 mL). The materials were mixed and refluxed for the appropriate time. The progress of the reaction was followed by TLC (n-hexane:ethyl acetate 3:1). After completion of the reaction, the mixture was filtered to remove the catalyst. After evaporation of the solvent, the crude product was re-crystallized from hot ethanol to obtain the pure compound.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 504-17-6.
