Position 3 is connected to [2- (2-methylbenzyl) acetamido], which is more complex and delicate. 2-methylbenzyl, such as branch extension, is based on benzene ring, and methyl is attached to the side chain, adding the hydrophobicity and steric resistance of the molecule; acetamido is connected to 2-methylbenzyl, and the complex is connected to the main structure, like a bridge, which affects the chemical properties and reactivity of the whole, and the affinity and movement of the left and right molecules.
4-oxygen generation, that is, position 4 is the generation of oxygen atoms. Oxygen has strong electronegativity, such as fixed Poseidon needle, which changes the density of the surrounding electron cloud, affects the polarity and reactivity of the molecule, and makes the molecule exhibit unique behavior in chemical reactions. 3,4-dihydropteridine, a heterocyclic structure of the molecular core, has a conjugated system, such as a resonant string, which endows the molecule with special electronic properties and optical properties, and plays a key role in optical, electrical and chemical reactions.
2,7-Disodium diacid salt, the carboxyl groups at positions 2 and 7 form sodium salts. This change is like a duck to water, which greatly enhances the water solubility of the molecule, enabling the molecule to exist stably in the aqueous solution environment and participate in various biochemical reactions. It is like a spirit integrated into the water system, freely shuttling through the chemical stage of life.
The various parts of this chemical structure cooperate with each other and restrict each other, jointly determining the physical and chemical properties and biological activities of the molecule. In many fields such as medicine and chemical industry, or for opening the door to new discoveries, or for building the foundation of new substances, all rely on the unique properties of this delicate structure.

Is (3E) -5- (ethylamino) -3- [2- (2-methylbenzyl) imino] -4-oxy-3,4-dihydropyrimidine-2,7-dione safe and non-toxic?
Guan Jun asked about (3E) -5- (ethylamino) -3- [2- (2-methylbenzyl) imino] -4-oxy-3,4-dihydropyrimidine-2,7-dione, which is an organic compound. Its safety and toxicity cannot be generalized, and more studies and data are needed to determine.
In general, the toxicity of an organic compound depends on its chemical structure, reactivity, metabolic pathway and other factors. This compound contains specific functional groups, such as amino, imino, carbonyl, etc. These groups may initiate biochemical reactions in organisms, but it is difficult to determine its toxicity based on the structure.
If you want to investigate its substantive safety, there are many experimental data. First, acute toxicity experiments can determine the degree of harm when it is exposed to a large number of organisms in a short period of time, and see if the organism has toxic symptoms, such as abnormal behavior and changes in physiological indicators. Second, chronic toxicity experiments can explore whether there are potential health risks after long-term low-dose exposure to organisms, such as damage to specific organs, reproductive and genetic effects. Third, mutagenic, carcinogenic and teratogenic experiments are also indispensable to determine whether it is genotoxic, carcinogenic and teratogenic.
In addition, the compounds behave differently in different environments and organisms. In the human body, individual differences, such as age, gender, health status, etc., can cause different reactions to the compound. In the environment, its degradation pathways and products are also related to ecological safety.
Therefore, based on the information provided so far, it is difficult to determine whether (3E) -5- (ethylamino) -3- [2- (2-methylbenzyl) imino] -4-oxide-3,4-dihydropyrimidine-2,7-dione is safe and non-toxic. It is necessary to conduct in-depth experimental research and analyze the data in detail before we can obtain a definitive conclusion.

In "Tiangong Kaiwu", the preparation method of (3E) -5- (acetamido) -3- [2- (2-methylbenzyl) sulfinyl] -4-oxide-3,4-dihydrothiophene-2,7-disulfonic acid disodium salt, although there is no direct correspondence in the original text, it can be speculated as follows according to the ancient chemical technology:
To make this product, the first raw material is selected. In the ancient context, it is necessary to find related materials containing acetamido, methylbenzyl, sulfinyl, thiophene and sulfonic acid groups, or to find sources from natural ores, plants, animal oils, etc. Such as natural sulphur ore or can provide sulfur elements, which is the starting point of sulfinyl and sulfonic acid groups; nitrogen-containing plants or can extract nitrogen-containing groups for the construction of acetamide groups.
After the raw materials are prepared, the reaction steps are carried out. Ancient chemical industry, often by the method of combining water and fire. The raw materials can be placed in the kettle first and boiled slowly to make the raw materials initially fused. This process requires fine control of the heat. If the fire is fierce, the raw materials will be easy to coke and lose their nature. If the fire is weak, the reaction will be slow and difficult to meet expectations.
When the raw materials are initially mixed, specific additives can be added in proportion. Although it is not as precise as modern chemistry, the ancients could also choose common things such as plant ash and lime based on experience to help the reaction advance. Among them, the dosage of additives needs to be repeatedly tried, and more are too much, and less are not effective. When the
reaction is carried out, observe the changes in the kettle, and wait for its color, taste, and state to meet specific standards, it is regarded as the initial completion of the reaction. Then, it may need to go through multiple purification methods, such as water immersion, filtration, evaporation crystallization, etc., to remove its impurities and obtain a pure product. When immersing in water, clean water needs to be selected, and the filtration equipment needs to be fine in order to effectively separate. Evaporative crystallization should also pay attention to the heat and time, so that the product can be precipitated in a good form.
The entire preparation process requires the full attention of craftsmen, with experience and patience, within the framework of traditional processes, as much as possible to achieve (3E) -5- (acetamido) -3- [2- (2-methylbenzyl) sulfinyl] -4-oxidation-3,4-dihydrothiophene-2,7-disulfonic acid disodium salt preparation.

I look at the things you have mentioned, and they are all listed by strange chemical names, but I have not heard of their usual situation in the price range of the market. Although "Tiangong Kaiwu" is a strange book, detailing all kinds of technical products, it may be difficult to find them in the market prices of these chemicals.
In today's world, the prices of chemicals are complex and changeable, which are related to the amount of raw materials, the difficulty of preparation, the wide range of uses, and the supply and demand of the market. And what is mentioned here may be fine chemical raw materials, or special chemical reagents, which are not ordinary and easy to use.
If you want to know the exact price, you can only get it if you ask today's chemical companies, chemical experts, or visit various professional chemical information platforms. The ancient "Tiangong Kaiwu" is really difficult to answer this question. The times are different, and the types of products are not available at that time.
