At the same time, in the field of organic synthetic chemistry, it can be used as a core module for the construction of complex organic molecules. With the difference in reactivity of bromine atoms, ethoxy groups and carboxyl groups, chemists can use various organic reactions, such as halogenation reactions, esterification reactions, coupling reactions, etc., to gradually build organic compounds with diverse structures and unique functions, which contribute to the development of organic synthetic chemistry.

To prepare 5-% deuterium-6- (1-methylethoxy) -3-p-toluenesulfonic acid, the following ancient methods can be used.
First take an appropriate amount of starting material, and precisely control its purity and dosage. In a clean reaction vessel, dissolve the raw material with a suitable organic solvent. This organic solvent should be compatible with the reactants and conducive to the reaction, such as anhydrous ether, dichloromethane, etc., depending on the characteristics of the raw material and the reaction requirements.
Then, slowly add specific reagents, and pay attention to the control of the rate and temperature during the addition process. If deuterium is introduced, a specific reagent containing deuterium can be selected, and the reaction mechanism can be gradually reacted according to the reaction mechanism, so that the deuterium atom precisely replaces the hydrogen atom at the desired In this step, the temperature should be maintained at a certain range, or cooled at low temperature, or moderately heated to promote the reaction to generate 5-% deuterium products.
When the deuterium substitution reaction reaches the expected level, start introducing the 6- (1-methylethoxy) part. Select a suitable halogenated 1-methylethoxy reagent, and under the catalytic action of a base, nucleophilic substitution reaction occurs with the intermediate containing deuterium. The type and dosage of bases also need to be precisely prepared. Common bases such as potassium carbonate, sodium hydroxide, etc. are selected according to the reaction activity and selectivity. The reaction conditions at this stage are also critical, and temperature and reaction time will affect the yield and purity of the product.
After completing the above two steps, the product has taken shape, but a 3-p-toluenesulfonic acid group needs to be introduced. The intermediate is reacted with p-toluenesulfonyl chloride in the presence of a suitable acid binding agent. The acid binding agent can be selected as pyridine, etc., to neutralize the hydrogen chloride generated by the reaction and promote the positive progress of the reaction. This reaction can successfully connect the p-toluenesulfonic acid group to the predetermined position at the appropriate temperature and time to generate the target product 5-% deuterium-6- (1-methylethoxy) -3-p-toluenesulfonic acid.
After the reaction is completed, it needs to be separated and purified. The product can be extracted from the reaction mixture by extraction with a suitable extractant, and then further purified by column chromatography, recrystallization, etc., to obtain high-purity target compounds.

Today, there are 5-alkane-6- (1-methylethoxy) -3-pyridinecarboxylic acids, which are available in the market price range. The price of this drug often varies for many reasons, making it difficult to determine.
First, the purity of the drug has a great impact on its price. If the purity is extremely high and there are few impurities, it is suitable for high-end scientific research or specific pharmaceutical preparation, and its price is high; if the purity is slightly lower, it is only used for general purposes, and the price is slightly lower.
Second, the manufacturer is also the key. A well-known producer with exquisite craftsmanship and strict quality control, although the price of the products is high, the quality is guaranteed; an emerging or unknown producer is competing for the market, and the price is close to the people.
Third, market supply and demand are of great importance. If demand is strong and supply is limited, prices will rise; if supply exceeds demand, producers may reduce prices and promote.
Overall, this 5-alkane-6- (1-methylethoxy) -3-pyridyl carboxylic acid is priced at market prices, ranging from tens to hundreds of dollars per gram. It is difficult to give an accurate price. Buyers should carefully review the quotations and product details of various manufacturers according to their own needs in order to obtain an affordable and suitable choice.

5-% -6- (1-methylethoxy) -3-pentynylic acid is a rare chemical compound, and its storage is of paramount importance. According to the concept of "Tiangong", the storage of materials needs to be considered in terms of physical properties. This acid is specific and sensitive to environmental factors.
First degree. It should be stored in a cool environment to avoid high chemical activity, decomposition or other chemical reactions due to high temperature. The ideal temperature should be controlled at 15 to 25 degrees Celsius, so it can be maintained.
Second degree. Because of its or the water's reaction, it is necessary to maintain the dry environment. The tide is easy to hydrolyze and other reactions, and its efficiency is improved. It should be placed in an environment with a phase resistance of 40% to 60%, and can be controlled by means of dryness and other means.
Furthermore, it needs to be protected from light. Light or actinic reaction, breaking its molecules. In dark containers such as brown bottles, and the storage should be dark, so as to avoid light and shadow.
In addition, if this acid is not connected to certain substances, or it is damaged. Therefore, it needs to be stored in a warehouse, and it should not be co-placed with oxidizing, original substances and acids to prevent anti-growth and ensure the stability of its chemical properties. In addition, 5-% -6- (1-methylethoxy) -3-valerynic acid can be properly stored by following the principles of coolness, dryness, light protection and incompatible substances.
