4,5-Dihydroxypyrimidine is an important intermediate in organic synthesis. There are many methods for its synthesis. Today, it is described in ancient French:
First, diethyl malonate and formamide are used as starting materials. First, diethyl malonate is placed in a reactor, an appropriate amount of alkali, such as sodium ethanol, is added, and stirred evenly to alkalize the system. Then slowly add formamide dropwise to control the dropwise speed and reaction temperature to prevent overreaction. After the dropwise addition is completed, heat up to a suitable temperature, and continue to stir the reaction for several hours. After the reaction is completed, through cooling, acidification, filtration and other steps, the crude product can be obtained, and then through recrystallization and other refining means, then pure 4,5-dihydroxypyrimidine is obtained. This is a classic synthesis route, the raw materials are easy to obtain, and the operation is relatively simple.
Second, urea and ethyl acetoacetate can also be used as raw materials. First, the urea is finely ground, and ethyl acetoacetate is co-placed in the reaction vessel. A little catalyst, such as zinc powder, is added. Heat the reaction at a certain temperature, and pay close attention to the changes in the system during the reaction process. After the reaction is completed, it is extracted with an appropriate solvent after cooling, and impurities are removed. After distillation and crystallization, 4,5-dihydroxypyrimidine can also be obtained. The reaction conditions of this method are mild, but the purity of the raw materials is relatively high.
Third, ethyl cyanoacetate and formamide are used as starting materials. First, ethyl cyanoacetate is mixed with formamide, and an appropriate amount of alkaline catalyst, such as sodium carbonate, is added. The reaction is reacted under heating conditions, and the reaction is continuously stirred during the reaction to promote full contact with the material. After the reaction is completed, the target product is finally obtained through the steps of neutralization, separation, and purification. Although this approach is slightly more complicated, the yield is quite high, and it is also used in industrial production.
All these synthesis methods have their own advantages and disadvantages. It is necessary to choose carefully according to actual needs, such as raw material cost, product purity, production scale and other factors.

4,5-Dihydroxypyrimidine is one of the organic compounds. Its physical and chemical properties are particularly important, and it is related to its application in various fields.
First of all, its physical properties. Under normal temperature, this substance is mostly in a solid state, or in a crystalline state, with a certain crystal shape. The color is either white or nearly colorless, and when it is pure, the texture is uniform. Its melting point is quite high. Due to the force between molecules, it needs a higher temperature to destroy its lattice structure and melt into a liquid state. The exact value of the melting point varies slightly depending on the preparation method and purity. Its solubility is also one of the characteristics. It has a certain solubility in water, but it is not very soluble. This is because although the molecular structure contains hydroxyl groups, it can form hydrogen bonds with water, but the existence of pyrimidine rings limits its water solubility. In organic solvents, such as ethanol, acetone, etc., the solubility may vary, and in ethanol, the solubility may be relatively high, due to the adaptation of ethanol and intermolecular forces.
As for chemical properties, the hydroxyl groups of 4,5-dihydroxypyrimidine are active. Esterification can occur. When it encounters the acid chloride and anhydride of organic or inorganic acids, the hydrogen in the hydroxyl group can be replaced by the acyl group to form the corresponding ester compound. This reaction is often an important step in organic synthesis, which can be used to modify the molecular structure and give it new properties. And because of its nitrogen-containing heterocyclic structure, the pyrimidine ring has a certain alkalinity, which can react with acids to form salts. This alkalinity is derived from the lone pair of electrons on the nitrogen atom, which can accept protons. In addition, it also manifests in redox reactions. Hydroxyl groups can be oxidized by appropriate oxidants and converted into other functional groups such as carbonyl groups. The control of reaction conditions is crucial, and it is related to the selectivity and purity of the product.
The physical and chemical properties of this compound make it have potential for application in many fields such as medicine, pesticides, materials, etc., and are valued by chemical research and industrial production.
