Alas! To prepare methyl 6-amino-3,5-dibromopyridine-2-carboxylic acid ester, the method is as follows.
Pyridine-2-carboxylic acid can be taken first, with appropriate bromination reagents, such as liquid bromine and appropriate catalysts, under suitable reaction conditions, such as in an inert solvent, temperature-controlled bromination reaction. This step aims to introduce bromine atoms into the 3rd and 5th positions of the pyridine ring to obtain 3,5-dibromopyridine-2-carboxylic acid. Pay attention to the progress of the reaction. The reaction can be monitored by thin-layer chromatography and other methods to stop the reaction in time to prevent excessive bromination.
Next, the resulting 3,5-dibromopyridine-2-carboxylic acid is mixed with methanol, an appropriate amount of catalyst, such as concentrated sulfuric acid, is added, and the esterification reaction is carried out under heating and reflux to convert the carboxyl group to the methyl ester group to obtain 3,5-dibromopyridine-2-carboxylic acid methyl ester. During this process, attention should be paid to the tightness of the reaction device and the control of temperature to ensure the smooth progress of the reaction.
Then, 3,5-dibromopyridine-2-carboxylic acid methyl ester is aminated. A suitable amination reagent, such as an alcohol solution of ammonia gas, can be selected to react under suitable pressure and temperature conditions to introduce the amino group into the 6 position of the pyridine ring, and finally obtain methyl 6-amino-3,5-dibromopyridine-2-carboxylic acid ester. After the reaction is completed, the pure product is obtained by separation and purification methods, such as column chromatography.
Each step of the reaction requires precise temperature control, timing control, and dosage control of reagents, and the cleanliness of the reaction environment is also required, so that the obtained product can meet the expected quality and yield.

Methyl 6-amino-3,5-dibromopyridine-2-carboxylic acid ester, the price of this product in the market is difficult to break. The change of its price is subject to many reasons.
One is related to the difficulty of preparation. If its preparation requires rare materials, complicated methods, and huge amounts of energy, its price will be high. If the preparation technology is often innovated, the yield will increase, the cost will decrease, and the price will also change.
Second, it depends on supply and demand. In the market, there is a wide demand for this product, but there are few suppliers, so the price will rise; if the supply exceeds the demand, the merchants will sell their goods, or reduce the price in order to sell.
Third, the competition in the city also has a great impact. If the merchants who control this product compete for customers, occupy the market, or have a price reduction policy; if there is only one company, there is no other competitor, the price can be high.
Fourth, the price of raw materials is also a major factor. If the price of raw materials rises, the cost of this product will increase, and the price of the market will also increase; if the price of raw materials falls, the opposite is true.
Fifth, changes in government decrees, regulations, and taxes can also cause price changes. If there is a tax increase, the merchant will turn it into a negative price; if there is a supportive policy, the cost may be reduced, and the price may also be reduced.
To sum up, the market price of methyl 6-amino-3,5-dibromopyridine-2-carboxylate must be carefully examined in preparation, supply and demand, competition, raw materials and decrees, before a more accurate judgment can be obtained. However, it is difficult to say how high or low the price is at this moment.

Methyl 6-amino-3,5-dibromopyridine-2-carboxylic acid ester is one of the organic compounds. During storage and transportation, many matters must be paid attention to.
First words storage, this compound should be placed in a cool, dry and well ventilated place. Cover because of its nature or affected by temperature and humidity, if it is in a high temperature and humid place, it may deteriorate.
