The synthesis method of fugmethyl-5-bromopyridine-2-carboxylic acid ester has been recorded in many books in the past, and the following is the common number.
First, pyridine-2-carboxylic acid is used as the starting material. Shilling pyridine-2-carboxylic acid and methanol are esterified under the catalysis of concentrated sulfuric acid, which is a classic esterification method. Sulfuric acid as a catalyst can promote the reaction of the two to form methyl pyridine-2-carboxylic acid. Then under suitable reaction conditions, bromination is carried out with a brominating agent such as N-bromosuccinimide (NBS). In an inert solvent such as carbon tetrachloride, under the action of an initiator such as benzoyl peroxide, NBS can selectively introduce bromine atoms at the 5-position of the pyridine ring to obtain methyl-5-bromopyridine-2-carboxylate.
Second, 5-bromopyridine can also be used as a starting material. 5-bromopyridine is first carboxylated with carbon dioxide under suitable catalyst and pressure conditions. Commonly used catalysts include metal-organic complexes, and this process can be carried out in a high-temperature and high-pressure reactor. After the reaction is completed, the carboxylation product is esterified with methanol under acid catalysis to obtain the target product methyl-5-bromopyridine-2-carboxylic acid ester.
Third, if 2-methylpyridine is used as the raw material. First bromide 2-methylpyridine to obtain 5-bromopyridine. Then oxidize the methyl to carboxyl with a suitable oxidant, such as potassium permanganate, to obtain 5-bromopyridine-2-carboxylic acid. Finally, methyl-5-bromopyridine-2-carboxylate can also be prepared by esterification with methanol under acid catalysis.
All these synthesis methods have their own advantages and disadvantages. According to actual needs, consider the availability of raw materials, the difficulty of reaction conditions, and the high or low yield to choose the best synthesis path.

Methyl-5-bromopyridine-2-carboxylic acid ester, the price of this product in the market is difficult to determine. The price of various products in the market often changes due to many reasons, such as the raw materials, the complexity of the workmanship, the amount of demand, the source of the goods, and even the different times.
If the raw materials are made, their quality is high and easy to obtain, and the price is slightly lower; if the raw materials are rare and difficult to find, the price must rise. And if the workmanship is simple, it saves manpower and material resources, and the price should be low; if the workmanship is complicated, it requires fine craftsmanship and special utensils, and the price is high. < Br >
The amount of demand, the shadow of the price is also huge. If everyone wants this thing, the supply is not enough, and the price will rise; if there are few requests, the supply exceeds the demand, and the price may drop. In addition, the origin of the goods is different. Long-distance transshipment is expensive and labor-intensive, and the price must be higher than that produced near the ground.
The passage of time can also make the price change. At different ages, the producers of raw materials may be rich or sorry, and the business policies are also different, all of which can cause price fluctuations. Therefore, if you want to know the market price of methyl-5-bromopyridine-2-carboxylate, you should study the situation, or consult the city and industry, to get a more accurate number.

Methyl-5-bromopyridine-2-carboxylic acid ester is a kind of organic compound. Its storage conditions are crucial, which is related to the stability and quality of this compound.
This compound should be stored in a cool and dry place. Cover a cool place to slow down its molecular movement and reduce the possibility of chemical reactions caused by excessive temperature; in a dry environment, avoid the risk of moisture hydrolysis. In hydrolysis, the reaction of molecular structure breaking in contact with water will also damage the purity and utility of this compound.
And should be stored in a well-ventilated place. With good ventilation, harmful volatiles can be quickly dispersed to prevent their accumulation from causing environmental hazards and personal injury. Because organic compounds are volatile, or produce harmful gases, good ventilation can ensure safety.
Furthermore, keep away from fires and heat sources. This compound may be flammable, and in case of open flames or hot topics, it may cause combustion or even explosion. Therefore, in storage, fireworks are strictly prohibited, and heat sources, such as heating, electrical heating parts, etc., should be kept away.
At the same time, it should be separated from oxidants, acids, alkalis, etc. Due to its active chemical properties, contact with such substances is prone to chemical reactions, or deterioration of compounds, and even lead to safety accidents.
In the choice of storage containers, it should not be ignored. A sealed container should be used to prevent volatilization and moisture intrusion. Sealed bottles and cans made of glass or plastic should be selected according to the characteristics of the compound, so that the seal is tight and no leakage is allowed.
