There are many different methods for synthesizing methyl 5-bromo-3-methylpyridine-2-carboxylic acid esters. One common method is to use 5-bromo-3-methylpyridine-2-carboxylic acid as the starting material. This acid is first mixed with methanol, and an appropriate amount of catalyst, such as concentrated sulfuric acid, is added to heat at a suitable temperature for esterification reaction. Concentrated sulfuric acid can promote the reaction, and increasing the temperature can increase the reaction rate. However, it is also necessary to pay attention that the temperature should not be too high to avoid side reactions. After the reaction is completed, the purified product can be obtained through distillation, extraction, column chromatography and other purification steps.
Second, the pyridine ring can be constructed first. Using suitable precursor compounds containing bromine, methyl and carboxyl groups as raw materials, by heterocyclic synthesis methods, such as Hantzsch pyridine synthesis method. The pyridine ring is first formed, and then the specific position on the ring is modified to achieve the synthesis of methyl 5-bromo-3-methyl pyridine-2-carboxylic acid ester. This process requires fine regulation of the reaction conditions, because while the pyridine ring is constructed, the introduction position and order of each substituent have a significant impact on the formation of the final product.
Another approach is to use halogenated pyridine derivatives as the starting materials. Through a selective halogen substitution reaction, bromine atoms and methyl groups are introduced at specific positions in the pyridine ring, followed by esterification of carboxyl groups. The key to this method lies in the selectivity and efficiency of the halogen substitution reaction. Appropriate reaction reagents and conditions need to be selected to ensure that bromine and methyl are introduced at the desired positions, and the esterification step needs to be carefully handled to ensure the purity and yield of the product.

Methyl-5-bromo-3-methylpyridine-2-carboxylic acid ester, which has a wide range of uses. In the field of pharmaceutical synthesis, it is often a key intermediate. Gein pyridine ring structure is common in many drug molecules, and bromine atoms, methyl groups and carboxylic acid ester groups can participate in various chemical reactions. Complex drug molecular structures can be constructed through reactions such as substitution and condensation.
Taking synthetic antibacterial drugs as an example, the final product can obtain antibacterial effect by modifying specific positions on its pyridine ring and connecting groups with antibacterial activity. In the field of pesticide creation, due to its unique structure, it has specific biological activities for some pests or pathogens. For example, through rational structural modification, pesticide products that have high-efficiency repellent effects on specific pests can be developed to protect crop growth.

Methyl-5-bromo-3-methylpyridine-2-carboxylic acid ester, the price of this product in the market is difficult to hide. Its price often varies due to many reasons, and it cannot be generalized.
The first to bear the brunt is the difficulty of its preparation. If the synthesis method is complicated, the raw materials required are rare and expensive, and the preparation process involves many fine steps and high-end technology, which requires a lot of manpower, material resources and time, and its price is high. On the contrary, if the preparation method is simple, the raw materials are easily available and inexpensive, the price may be accessible to the people.
Furthermore, the supply and demand of the market is also the key. If there is a strong demand for this product in chemical, pharmaceutical and other fields, but the supply is limited, the supply is in short supply, and its price will rise. However, if the market demand is small, but the supply is more than abundant, the price will decline.
In addition, the difference between merchants also has an impact. Different merchants set different prices due to different cost control and business strategies. Large merchants may have lower costs due to scale effects, or higher prices due to the advantages of brands and services; small merchants may have high costs, but they may compete for the market and offer customers at low prices. Therefore, in order to know the exact market price of methyl-5-bromo-3-methylpyridine-2-carboxylate, it is necessary to carefully observe the current market situation and comprehensively consider the above factors to obtain a more accurate price.

Methyl 5-bromo-3-methylpyridine-2-carboxylic acid esters are organic compounds. When storing and transporting, all matters need to be handled with caution.
