(3E) After removing 5, removing (acetonitrile hydroxyl), going through 4 oxidation and 3 steps, entering the process of [2 - (3 - furan ribosyl) urea], and then going through 3,4 - dioxy thiophene, 2,7 - dioxy diberyllium and other changes, and finally obtaining all kinds of useful things.
One of its uses is to assist in the synthesis of 3,4 - dioxy thiophene. This compound is quite useful in the field of electronic materials, which can improve the electrical conductivity of materials and make electronic products better. Furthermore, 2,7-diberyllium dioxalate is indispensable in the manufacture of special alloys, which can enhance the strength and corrosion resistance of alloys, and is widely used in high-end fields such as aerospace.
And (3E) lays the foundation for subsequent reactions in the removal of (acetonitrile hydroxyl) and other steps. After 4 oxidation steps, the product is endowed with specific chemical properties. As for the [2 - (3-furan ribosyl) urea group] link, it is of great significance to the structural shaping of the product.
In conclusion, 3,4-dioxythiophene and 2,7-diberyllium dicarboxylate obtained by a series of complex changes in (3E) play key roles in many fields such as electronics and alloy manufacturing, and are indeed important sources of chemical materials.

To prepare (3E) -5- (isopropylamino) -4-oxo-3- [2- (3-furanoyl) acetamido] -3,4-dihydropyrimidine-2,7-dione, the method is as follows:
First take an appropriate amount of starting materials, according to the ancient method, in delicate steps, step by step. First make a reactant in a specific reaction environment, or in a warm state, or in a specific solvent atmosphere, and combine with others. If a compound with active groups interacts with a corresponding reactive group according to the laws of chemistry.
During this time, control the appropriate temperature and pressure to observe the progress of the reaction. If the temperature is too high, the reaction will be too aggressive and the product will be impure; if the temperature is too low, the reaction will be slow and time-consuming. The pressure also needs to be appropriate to make the collision frequency between molecules appropriate to promote the smooth progress of the reaction.
When the first step of the reaction is completed, the product will gradually take shape, but further modification is required. At this time, new reactants are introduced and ingeniously designed to couple the two under specific conditions. Or with the help of the force of the catalyst, the reaction rate will be accelerated, so that the rearrangement and bonding of the atoms will proceed in the expected direction.
After many twists and turns, each step of the reaction is as expected, and each intermediate product has also been carefully treated and purified to remove its impurities and leave its essence. Finally, the reactants are skillfully combined to obtain the product of (3E) -5- (isopropylamino) -4-oxo-3- [2- (3-furanoyl) acetamido] -3,4-dihydropyrimidine-2,7-dione. The whole process of preparation requires careful operation, and it must not be sloppy at all. If there is a slight mistake, all previous efforts will be wasted. This is the main method of preparation.

The objects recorded in "Tiangong Kaiwu" have different shapes and properties. Jin Yan (3E) - 5- (acetonitrile hydroxyl) - 4-oxo-3- [2- (3-thiophenoformyl) acetamido] - 3,4-dihydropyrimidine-2,7-diketone disodium salt, this substance has multiple physical properties.
Its appearance is often a specific shape, or a crystalline solid with a delicate texture. Under light, it may have a crystal clear state, just like jade chips, shining brightly. Its color may be pure and white, like the first snow in winter, or slightly yellow, like the moonlight on an autumn night.
Melting point is one of its important physical properties. When the outside temperature rises to a specific value, this substance will melt like ice in spring, gradually transforming from solid to liquid. This temperature is the marker of its melting point. Accurate measurement can provide a basis for identification and use.
Solubility cannot be ignored. In water, it may slowly dissolve, just like salt melts in soup to form a uniform solution. In organic solvents, its dissolution varies, or it is like a fish in water, which melts quickly, or it is like oil and water, which is difficult to miscible. This is related to the properties of the solvent.
In terms of density, the mass per unit volume is either as light as a feather or as heavy as lead, which is different from that of common substances. This density characteristic has an impact on its storage and transportation.
The physical properties of this object are of great significance in various fields such as chemical industry and medicine. Only by understanding its properties can we make good use of it, give full play to its maximum effectiveness, and bring many conveniences and benefits to the world.

In "Tianwen Kaiwu", (3E) -5- (ethylcyano) -4-oxo-3- [2 - (3-thiophenoformyl) acetyl] -3,4-dihydropyrimidine-2,7-diketone dicobalt The safety of this compound is related to people's livelihood and cannot be ignored.
This compound has complex properties. From the perspective of its structure, groups such as ethylcyano and thiophenoformyl give it unique chemical properties. In experimental investigation, it is necessary to observe its reaction with surrounding substances.
However, it is difficult to find a direct statement on the safety of this specific compound in ancient books. But similar things can be compared. Looking at ancient alchemy, warlocks combine various medicines, and there is a risk of explosion and poison from time to time, all because the physical properties are unknown. Today's (3E) -5- (ethcyano) -4-oxo-3- [2 - (3-thienoformyl) acetyl] -3,4-dihydropyrimidine-2,7-diketone dicobalt, or there is also the possibility of high reactivity, mixed with other things, or react violently, generate heat, produce gas, and cause the danger of container bursting.
And looking at ancient medicines, asarum is nothing but money, and too much is poisonous. If this compound is involved in the fields of medicine, food and other fields, it is crucial to control the amount. Although its structure is exquisite, or has specific effects, it is slightly careless, or it may enter the human body, damage the internal organs, and disrupt qi and blood.
Also think of ancient utensils, the material is not properly matched, and the utensils are easy to destroy. If this compound is used in industry, it is incompatible with the material of production equipment, or causes equipment corrosion, leakage of materials, pollution of the environment, and harm to life.
In summary, the safety of (3E) -5- (ethcyano) -4-oxo-3- [2 - (3-thienoformyl) acetyl] -3,4-dihydropyrimidine-2,7-diketone dicobalt should be carefully investigated and its properties should be carefully.
