The synthesis method of methyl 2-chloropyridine-3-carboxylic acid ester has been studied by chemists throughout the ages, and the methods are also rich and diverse. One common one is to use 2-chloropyridine-3-carboxylic acid and methanol as raw materials, under acid catalysis, the esterification reaction is carried out. In this process, sulfuric acid, p-toluenesulfonic acid and other catalysts are often used. Mix the two, heat and reflux, and after several hours or even tens of hours, the reaction is completed, and the product can be purified by distillation, extraction, column chromatography, etc.
Second, 2-chloronicotinyl chloride can also be used to react with sodium methoxide. 2-Chloronicotinyl chloride is prepared first, and then reacts with sodium methoxide in appropriate solvents, such as tetrahydrofuran, dichloromethane, etc. The reaction conditions are mild, but the preparation of raw materials may require multiple steps, and the operation requirements are also high. After the reaction is completed, the target product is obtained by washing, drying, distillation and other steps.
There is also 2-chloropyridine-3-nitrile as the starting material, which is first hydrolyzed to acid and then esterified with methanol. Although the steps are slightly complicated, the raw materials are easy to obtain. If the conditions of each step are properly controlled, good yields can be obtained. Methyl 2-chloropyridine-3-carboxylic acid ester was obtained by the separation and purification of methyl 2-chloropyridine-3-carboxylate catalyzed by acid and base during hydrolysis and esterification.

Methyl-2-chloropyridine-3-carboxylic acid ester is one of the organic compounds. It has unique physical and chemical properties.
Looking at its physical properties, under room temperature and pressure, it is often in a liquid or solid state, but the exact form varies depending on specific conditions. The substance has a specific melting point and boiling point, and the values of melting point and boiling point are crucial to the identification and purification of this compound. In terms of solubility, some organic solvents, such as ethanol and ether, exhibit some solubility, but are difficult to dissolve in water. This solubility characteristic is of great significance in the process of organic synthesis and separation, and can be used to separate and purify compounds by means of different solvent characteristics.
When it comes to chemical properties, its structure contains ester groups and chlorine atoms, so it has corresponding chemical reactivity. The ester group can undergo hydrolysis reaction, and under acidic or alkaline conditions, it can hydrolyze to form 2-chloropyridine-3-carboxylic acid and methanol. Under alkaline conditions, the hydrolysis reaction is more rapid and thorough. Chlorine atoms are also highly active and can participate in nucleophilic substitution reactions. When encountering nucleophilic reagents, chlorine atoms will be replaced by nucleophilic reagents, and then a series of compounds with different structures can be derived. This reaction property makes methyl-2-chloropyridine-3-carboxylic acid esters an important intermediate in organic synthesis. With nucleophilic substitution and hydrolysis, a variety of organic compounds containing pyridine structures can be prepared, which have important application values in pharmaceutical chemistry, materials science and other fields.

The price of methyl 2-chloropyridine-3-carboxylic acid ester is difficult to determine in the market. The price of methyl 2-chloropyridine-3-carboxylic acid ester is often changed due to various reasons, such as the supply and demand of the market, the cost of production, the quality of quality, and even the circulation of time.
Looking at the past, the price of chemistry mostly depends on the law of supply and demand. If there are many people who want it, and there are few people who supply it, the price will rise; on the contrary, if the supply exceeds the demand, the price will be depressed. Methyl 2-chloropyridine-3-carboxylic acid ester is used in the chemical industry, medicine and other industries, and the amount required varies with the rise and fall of various industries.
Furthermore, the cost of the system is also a major factor. The price of raw materials, the complexity of the workmanship, and the level of technology all involve costs. If the raw materials are rare, or the workmanship is complex, the cost will increase, and the price will also be high. And the quality is also related to the price. The superior one is always high; the inferior one is low.
Also, the flow of time also affects the price. In case of fluctuations in the market, changes in politics, and sudden disasters, the price may change. Therefore, if you want to know the exact price, you need to always look at the market conditions and consult the merchants, or you can approach it. However, the market is not constant, and the price is also uncertain. You must always pay attention to it before you can get its approximate price.
