The synthesis of 2-% hydrocarbon-5- (trihydrocarbon methyl) pyrimidinic acid covers a variety of pathways, which are described in detail today.
First, the nucleophilic substitution reaction can be carried out by the corresponding hydrocarbon halide and the parent of the pyrimidine-containing structure in a suitable base and solvent environment. Among them, the choice of base is quite critical, such as potassium carbonate, sodium carbonate, etc., which can promote the smooth departure of the leaving group of the halide, and the solvent is more polar aprotic solvents such as dimethylformamide (DMF) and acetonitrile to facilitate the reaction. During the reaction, precise temperature control is required, depending on the activity of the substrate, the temperature may be between room temperature and tens of degrees Celsius. After the nucleophilic substitution is completed, the target 2-% hydrocarbon-5- (trihydrocarbon methyl) pyrimidine acid can be obtained by acidification.
Second, pyrimidine is used as the starting material, and the hydrocarbon is first modified. Organometallic reagents, such as Grignard reagents or lithium reagents, can react with the active check point on the pyrimidine ring to introduce hydrocarbon groups. Subsequently, through a specific reaction, the methyl group is gradually converted into a trihydrocarbon methyl structure. This process requires a clever connection of multiple steps, and each step requires fine control of the reaction conditions, such as reaction time, ratio of reactants, etc.
Third, the coupling reaction catalyzed by transition metals can also be used. Select suitable transition metal catalysts, such as palladium, copper, etc., with specific ligands, to couple the halides or borates containing hydrocarbyl groups with pyrimidine derivatives. This method has the advantages of high efficiency and good selectivity, but the cost of catalysts and ligands is high, and the requirements for reaction equipment and operation are also quite strict.
Or it can start from pyrimidine derivatives and gradually construct the structure of 2-% hydrocarbon-5- (trihydrocarbon methyl) pyrimidinic acid through multi-step functional group conversion. For example, the substituents on the pyrimidine ring are oxidized, reduced, and substituted first to achieve the desired structure, and then cyclized and subsequent modified to obtain the final target product.
Synthesis of this compound, each method has its own advantages and disadvantages, and the appropriate synthesis path should be carefully selected according to actual conditions, such as the availability of raw materials, cost, and ease of control of reaction conditions.

For 2-% Ming-5- (triming methyl) imidazole acetic acid, many matters need to be paid attention to during storage and transportation.
The tightness of the first heavy packaging. This is to prevent it from reacting with external substances and causing quality damage. When in a suitable container, seal it tightly to avoid exposure to the air, so as to avoid deliquescence or chemical reactions with various components in the air, such as oxygen, carbon dioxide, etc., and change its chemical properties.
The second is the temperature and humidity of the environment. It should be stored in a cool and dry place. If the temperature is too high, it may cause it to evaporate and decompose faster; if the humidity is too high, it will easily absorb moisture and affect its purity and stability. Generally speaking, the temperature should be controlled below [X] ° C, and the relative humidity should be within [X]%. The exact value depends on its specific physical and chemical properties.
Furthermore, when transporting, it must be handled lightly. This substance may have a certain sensitivity, rough handling, or damage to the package, causing leakage, not only causing material loss, but also causing safety hazards due to the action of leaked substances and the surrounding environment. And during transportation, it is also necessary to maintain stable temperature and humidity conditions to prevent it from changing due to sudden changes in the environment.
In addition, it needs to be stored and transported in categories with other chemicals. Due to its chemical properties, or incompatibility with certain substances, if it is mixed, mixed, or causes violent chemical reactions, such as combustion, explosion and other serious accidents. Therefore, it is necessary to know its chemical properties in detail, and arrange the storage and transportation methods reasonably according to its characteristics and taboos, so as to ensure the safety of the whole storage and transportation process.

Recently, the fluctuation of the price state of 2-hydroxy- 5 - (triethylmethyl) thiazole acetic acid in the market has been observed by everyone. The reason for this is that the changes in the business market and the mixing of various factors have caused the price to fluctuate.
First, the balance between supply and demand is the pivotal demand of the price. If there are many people who want it, and the supply is small, the price will rise; on the contrary, the supply exceeds the demand, and the price will drop. Recently, or because the downstream industries are booming, those who use this product are becoming more and more prosperous, and the demand has increased sharply. Those who produce it have not been able to expand their production capacity quickly, and the supply is difficult to respond to the demand, so the price has a tendency to rise.
Second, the price of raw materials is also a constraint. The production of 2-hydroxy- 5 - (triethylmethyl) thiazole acetic acid depends on all kinds of raw materials. The price of raw materials increases, and the cost of the production will increase. In order to protect their profits, the merchant will also increase the price of the sale. If the origin of raw materials changes over time, or the government regulations change, the supply of raw materials will be unstable, and price fluctuations will inevitably be inevitable.
Third, the direction of the government has a huge impact. The regulations promulgated by the government have contracts on production, sales and transportation. If strict regulations are established to promote enterprises to improve their skills and improve their environment, or if enterprises increase their fees due to compliance with regulations, this fee must be transferred to the price. Or give support to a certain industry to increase its production, which can also make supply change, and the price follow.
Fourth, the competition in the city should not be underestimated. The industry is crowded, and the competition will be fierce. Or there are enterprises to expand their cities, luring customers at low prices, causing prices to drop; however, there are also enterprises that rely on their technical excellence and good quality to keep their high prices, and the attitude of the market is different.
Overall, the market price of 2-hydroxy- 5 - (triethylmethyl) thiazole acetic acid is driven by supply and demand, raw materials, policies and regulations, and competition. The increase and suppression of its price cannot be determined. The industry needs to observe the changes in the market and find good strategies to respond to them.
