This substance is acidic because it contains a carboxyl group (-COOH). The hydrogen in the carboxyl group can be partially ionized, making its aqueous solution acidic and capable of neutralizing with bases. If reacted with sodium hydroxide, the hydrogen in the carboxyl group is combined with hydroxide to form water to form the corresponding carboxylate. The reaction formula is: R - COOH + NaOH → R - COONa + H 2O O (R stands for the rest of 2-trifluoromethyl-6-chloro-5-formylbenzoic acid).
It has the characteristics of esterification reaction. Under the catalysis of concentrated sulfuric acid and heating conditions, the carboxyl group can be esterified with alcohol. Taking the reaction with ethanol as an example, an ester and water are formed. The reaction formula is: R-COOH + C 2O H OH $\ underset {\ triangle} {\ overset {concentrated sulfuric acid }{=\!=\!=}}$ R - COOC 2O H + H 2O O. This reaction is a reversible reaction. In practice, the equilibrium is often shifted right by increasing the concentration of the reactant or separating the product in time to improve the ester yield.
Its carbonyl group (-C = O) has a certain reactivity and can undergo an addition reaction. For example, under certain conditions, it can be added with some nucleophilic reagents. Because the carbon-oxygen double bond electron cloud in the carbonyl group is biased towards oxygen, the carbon atom is partially positively charged and vulnerable to attack by nucleophiles.
It may also undergo a substitution reaction. The hydrogen atom on the benzene ring can be replaced by other atoms or atomic groups under appropriate conditions. For example, under the action of a catalyst, substitution reactions such as halogenation and nitrification can occur. Because the benzene ring is a conjugated system, the electron cloud distribution is special, so that the hydrogen on the benzene ring has a certain activity and is easily replaced.
In summary, 2-trifluoromethyl-6-chloro-5-formylbenzoic acid has various chemical properties such as acidity, esterification, addition and substitution due to its carboxyl, carbonyl and benzene ring structures.

To prepare di-triethylmethyl-6-chloro-5-paranitronidazole acid, the method is as follows:
First take an appropriate amount of starting materials, follow a specific ratio, and mix the triethylmethyl-containing compound with the chlorine-containing reagent. In the reactor, control the temperature, pressure and other conditions to make the two substitution reactions occur. At the beginning of the reaction, slowly heat up to gradually activate the reactants and increase the chance of collision between molecules to promote the smooth progress of the reaction. In the meantime, it is necessary to pay close attention to the progress of the reaction, and monitor the degree of reaction in real time by means such as thin-layer chromatography. < Br >
After the substitution of the chlorine-containing part is relatively complete, the reagent that can form the nitrozolic acid structure is introduced. In this process, the choice of solvent is very critical. It is appropriate to choose a solvent that has good compatibility with the reactants and products and has no inhibitory effect on the reaction. When the
reaction is carried out, it is also necessary to pay attention to the pH of the reaction system. By adding an appropriate amount of acid-base regulator dropwise, the system is maintained in a suitable acid-base environment to ensure the direction and rate of the reaction.
After the reaction is roughly completed and the product is formed, the reaction mixture is post-treated. First, the product is extracted from the reaction system with a suitable extractant to initially separate the product from the impurities. The purity of the product is further improved by distillation, recrystallization and other purification methods. During distillation, the temperature is precisely controlled to separate the product and impurities according to the difference in boiling point; recrystallization selects suitable solvents and operating conditions according to the solubility of the product in different solvents to obtain high-purity crystal products. In this way, a relatively pure di-triethylmethyl-6-chloro-5-nitazolic acid can be obtained.

Wen Jun inquired about the market price of di-triethylmethyl-6-chloro-5-p-toluenesulfonic acid. The price of this product varies from time to time in the market, and also varies with quality, quantity, and supply and demand.
If it is of high quality, its price may be high. Because the process of refining is complex and the materials used are also refined, it is worth a lot. There are many people in the market who want it, and the supply is small, the price will increase; if the supply exceeds the demand, the price will drop.
The amount is also related to the price. If you buy in bulk, the merchant may give a discount in order to promote sales, and the total price is spread, the unit value will drop; if you only ask for a small amount, for emergency needs, the merchant will consider the cost, and the price may be slightly higher.
In addition, the price is also different depending on the production area. Those produced here, or due to the convenience of geographical location, have a slightly lower cost, and the price is also cheaper than others; and those shipped far away, with the addition of freight, taxes, and fees, the price will increase.
The current price is about gold per catty [X]. However, this is not a constant value, and there may be changes between ten months. To know the exact price, it is advisable to consult the drug store merchants, or observe changes in the market, to get a real-time price.

2-triethyl-6-chloro-5-p-benzoic acid and other substances are often stored under specific conditions due to chemical properties and practical application requirements. Analogy can be found in the storage of many materials involved in "Tiangong Kaiwu". Its storage often needs to consider a variety of factors to prevent deterioration, loss or danger.
From the environment, it needs to be placed in a cool and dry place. Because its chemical structure contains specific functional groups, it is sensitive to temperature and humidity. If the environment is hot and hot, the structure of triethyl may change, and the activity of chlorine atoms may also be affected, or cause reactions such as decomposition and polymerization, which will damage its purity and quality.
For container selection, inert materials, such as glass, specific plastics, etc. Because triethyl-chlorine-p-benzoic acid has a certain chemical activity, if the container material reacts with it, it will not only contaminate the material, but also change its chemical composition. Like a metal container, or complexes or reacts with some of its groups.
When storing, it should also be kept away from fire sources and oxidants. The chemical structure of this substance determines its flammability and oxidation sensitivity. In case of an open flame, or due to intense combustion of organic groups; in case of strong oxidants, triethyl, chlorine and other structures may be oxidized, causing chemical properties to change and lose their original efficacy.
In addition, pay attention to the well-ventilated storage space. To prevent the accumulation of volatile trace substances, one is to avoid the formation of flammable and explosive mixtures, and the other is to prevent long-term exposure of workers to potentially harmful gas environments, and to ensure personal safety and material stability. The combination of these conditions can achieve the purpose of properly storing 2-triethyl-6-chloro-5-p-benzoic acid.
