Methyl 2-bromothiazole-5-carboxylate is an important compound in organic synthesis, and its synthesis methods are numerous, which are described in detail below.
First, 2-amino-5-carboxythiazole is used as the starting material. Protect the amino group first to prevent side reactions in subsequent reactions. Often acylating reagents, such as acetic anhydride or benzoyl chloride, react with the amino group to form the corresponding amide derivative in the presence of an appropriate base, such as pyridine or triethylamine, to achieve amino protection. Subsequently, in a suitable solvent, such as dichloromethane or chloroform, at low temperature, the protected 2-amino-5-carboxylthiazole is reacted with a brominating agent, such as N-bromosuccinimide (NBS) or bromine, and bromine atoms are introduced at the 2-position of the thiazole ring. Finally, the deprotection reaction is carried out under acidic or basic conditions, and then the esterification reaction is carried out with methanol in the presence of a catalyst such as concentrated sulfuric acid to obtain Methyl 2-bromothiazole-5-carboxylate.
Second, the 2-halo-5-cyanothiazole is used as the raw material. First, 2-halo-5-cyanothiazole is hydrolyzed under basic conditions to convert the cyano group into a carboxyl group. The commonly used base is an aqueous solution of sodium hydroxide or potassium hydroxide, and it is reacted under heating conditions to obtain 2-halo-5-carboxythiazole. Next, it is esterified with methanol under the catalysis of concentrated sulfuric acid to generate the corresponding methyl ester. Finally, through a halogen atom exchange reaction, a brominating reagent, such as a mixture of potassium bromide and copper powder, is used to replace the halogen atom at the 2-position with a bromine atom under appropriate solvent and heating conditions, thereby obtaining the target product.
Third, thiazole-5-carboxylic acid is used as the starting material. Methyl thiazole-5-carboxylate is synthesized by esterification of thiazole-5-carboxylate with methanol catalyzed by concentrated sulfuric acid. Methyl 2-bromothiazole-5-carboxylate is then synthesized by reacting with a brominating reagent, such as acetic acid solution of hydrogen bromide, in the presence of light or an initiator.

The price of methyl-2-bromothiazole-5-carboxylic acid ester in the market is difficult to determine. The market price of methyl-2-bromothiazole-5-carboxylic acid ester is constantly changing due to many reasons, such as the trend of supply and demand, the coarseness of the manufacturing process, the price of raw materials, the rise and fall of market conditions, and even the circulation of seasons and regional differences.
If you look at the chemical industry in the past, the supply and demand situation will bear the brunt. If there is a strong demand for methyl-2-bromothiazole-5-carboxylic acid ester in the market, and the output is not enough, its price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
The ingenuity of the craftsmanship also depends on the price. A fine method can reduce its consumption and increase its quality, and the price of the product may be excellent; a crude method results in large consumption and inferior quality, and the price may be different.
The price of raw materials is its foundation. If raw materials are easy to obtain and cheap, the cost will drop, and the price will follow; if raw materials are rare, the cost will be high, and the price will rise.
Different regions have different prices. Prosperous and well-connected places, logistics is convenient, or because of competition, the price may be leveled; remote places, transportation is difficult, costs are superimposed, and the price may be slightly higher.
Changes in seasons can also be affected. At a specific time, or due to the benefits of production, or due to differences in demand, prices fluctuate.
To know the exact price, you should check the market conditions carefully and consult suppliers, traders, or chemical information platforms to obtain a near-real price.

Methyl-2-bromothiazole-5-carboxylate is an organic compound, and there are indeed many things to pay attention to when storing and transporting.
The first word storage, because of its nature or sensitive to environmental factors, should be placed in a cool, dry and well-ventilated place. This is due to humid environment or moisture-causing compounds, which affects their purity and stability. And high temperature may also cause chemical reactions and cause them to deteriorate. Keep away from fires and heat sources to prevent fire and explosion. Because of its flammability, it may be dangerous in case of open flames, hot topics or. In addition, it should be stored separately from oxidants, acids, bases, etc., and should not be mixed. Dangerous due to chemical reactions between the compound and these substances or prone to occur. The storage place also needs to be equipped with suitable materials to contain the leakage, so that it can be dealt with in time if it is accidentally leaked.
As for transportation, it is also not to be slack. Be sure to ensure that the packaging is complete and well sealed before transportation. If the packaging is damaged, the compound or leakage will not only pollute the environment, but also pose a threat to the transportation personnel. During transportation, relevant regulations and operating procedures should be followed. The transportation vehicle should be equipped with corresponding fire protection equipment and leakage emergency treatment equipment. In case of accidents during transportation, it can respond quickly. To avoid exposure to the sun, rain, and prevent the adverse effects of high temperature and humid environment on the compound. When transporting, it is also necessary to pay attention to the isolation of other goods, and do not transport with contraband items to ensure the safety of transportation.
