To prepare 6- (4-methoxybenzoyloxy) benzoic acid-3-sulfonic acid, there are many ways to synthesize it.
First, the corresponding benzoyl chloride and phenolic compounds can be esterified under the catalysis of bases, and then the obtained product can be sulfonated. For example, the benzoyl chloride containing methoxy group and the phenol containing carboxyl group are first taken. In the presence of bases such as pyridine, the two are esterified to form ester bonds. This process needs to be controlled by temperature and time to prevent side reactions. Later, it is sulfonated with a suitable sulfonating agent, such as fuming sulfuric acid, and under suitable conditions, the sulfonic acid group is introduced to the target position.
Second, the benzene ring can be sulfonated first, and then the esterification reaction can be carried out. That is, the benzene ring compound containing methoxy group is treated with a suitable sulfonating agent, and the sulfonic acid group is successfully introduced. Then the esterification step is completed by acid chloride or acid anhydride and carboxyl phenols under base catalysis to construct the desired ester structure. The key to this path lies in the selective control of the sulfonation check point and the optimization of the subsequent esterification reaction conditions to avoid the influence of the introduced sulfonic acid group.
Third, the protective group strategy can be considered. If some groups in the molecule are easy to interfere with the target reaction during the reaction, they can be protected first. For example, the carboxyl group is first protected with a suitable protective group (such as methyl ester), and the protective group is removed after the sulfonation of the benzene ring and the subsequent connection with the benzoyl group are completed to obtain the target product. This strategy requires careful selection of protective groups and deprotection conditions to ensure that the reaction is efficient and does not affect other structures.
All synthesis methods have advantages and disadvantages, and need to be based on the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, and the purity requirements of the product.

To determine the purity of 6- (methyl 4-methoxybenzoyloxybenzoate) -3-quinolinic acid, the following method can be used:
First take an appropriate amount of 6- (methyl 4-methoxybenzoyloxybenzoate) -3-quinolinic acid sample and precisely weigh its quality. Then, choose an appropriate analytical method, such as high-performance liquid chromatography (HPLC), which is a common and accurate purity determination method.
When analyzing by HPLC, a suitable chromatographic column should be prepared, and a reverse-phase column or a normal-phase column should be selected according to the characteristics of the sample to achieve a good separation effect. Select a specific mobile phase, which is mixed with different proportions of organic solvent and buffer. With its different polarity, the components in the sample have different retention times in the column to achieve separation. The sample is injected into the chromatograph, driven by the mobile phase, the components are separated one by one, and the chromatogram is detected and recorded by the detector.
According to the obtained chromatogram, the purity of the sample is calculated by the ratio of the main peak area to the total peak area. However, it should be noted that the use of standards is crucial in this process. Take the known purity of 6- (4-methoxybenzoyloxybenzoic acid methyl ester) - 3-quinolinic acid standard, according to the same method of injection analysis, in order to establish a reliable quantitative relationship.
In addition to HPLC, melting point determination can also be used to assist judgment. Pure substances have a specific melting point range. If the purity of the sample is high, the melting point should be consistent with the literature value, and the melting range is narrow; if impurities are contained, the melting point is often offset, and the melting range is also widened.
In addition, elemental analysis can measure the proportion of each element in the sample, and the purity can also be observed compared with the theoretical value. The purity of 6 - (4 - methoxybenzoyl methyl benzoate) - 3 - quinolinic acid can be measured accurately by using these methods and confirming each other.

6 - (4 - methoxybenzyloxycarbonylbenzyloxycarbonylbenzyloxycarbonylmethylbenzyl) to its 3 - boronic acid storage conditions are: should be placed in a cool, dry and well ventilated place. This substance is sensitive to temperature and humidity, and high temperature or high humidity environment can easily cause its properties to change or even fail. Therefore, the storage temperature should be controlled between 2 - 8 ° C, so as to ensure the stability of its chemical properties. At the same time, it needs to be stored in a sealed container to prevent oxidation reactions in contact with air, which will affect its quality. Storage should be kept away from fire sources, heat sources and strong oxidants to avoid dangerous reactions. After use, it is necessary to seal it in time to prevent external factors from adversely affecting the remaining material, so as to ensure that the material can maintain good performance and quality during storage for subsequent use.

I think what you are asking is about the market price range of 6- (4-methoxybenzyloxy carbonyl benzyloxy carbonyl formamido) to its 3-pyridyl acid. However, this chemical substance is very professional and uncommon, and few people know it.
If you want to know its market price, you should look for it from many sources. First, you can consult the merchants specializing in chemical reagents. They are often involved in the sale of various chemicals, or can know the price of this 6- (4-methoxybenzyloxy carbonyl benzyloxy carbonyl carbonyl formamido) - 3-pyridyl acid. Second, professionals who have visited the chemical industry, such as practitioners in chemical companies and researchers in the chemical field, have been in this field for a long time, or are quite familiar with the price of various chemical products, or can solve your doubts.
However, because I do not know the specific characteristics, uses, market supply and demand of this chemical, it is difficult to determine its price range. Its price may fluctuate due to various factors such as purity, output, and market demand. If the purity is extremely high, the price must be higher than that of ordinary purity; if the market demand is strong and the output is limited, the price may rise; conversely, if the supply exceeds the demand, the price may decline. In short, if you want to get an accurate price range, you need to go to the relevant market, enterprise, or professional chemical information platform for detailed investigation.
