Methyl 6-methoxypyridine-3-carboxylic acid ester is one of the organic compounds. Its physical properties are quite important, and I will describe them in detail for you.
First word appearance, this substance is usually in the form of a white to off-white crystalline powder, with a fine texture and a rather regular appearance. Its melting point is also a key physical property, about [X] ° C. The determination of the melting point can verify its purity. If the purity is high, the melting point range is narrow, and vice versa.
Furthermore, the solubility of this substance cannot be ignored. In organic solvents, such as ethanol, acetone, etc., it has a certain solubility. In ethanol, it is more soluble after a little heating, forming a clear solution; in water, its solubility is poor, only slightly soluble. The difference in solubility is due to the interaction between the lipophilic methyl group and methoxy group in its molecular structure, and the relatively hydrophilic pyridine ring and carboxylic acid ester group, which cause it to behave differently in different solvents.
In addition, the density of this substance is also a specific value, about [X] g/cm ³. Density is an inherent property of the substance and is very important for identification and related process design. Under normal conditions, its stability is good, but when it encounters strong oxidizing agents, strong acids or strong bases, it may react chemically, causing its structure and properties to change.
The vapor pressure of this substance is low, and it evaporates slowly at room temperature and pressure. This property makes it less susceptible to loss due to volatilization during storage and use, and also reduces the risk of pollution caused by diffusion in the air.
In conclusion, the physical properties of methyl 6-methoxypyridine-3-carboxylate are of great significance in its synthesis, separation, storage and application, and must be carefully considered.

There are various ways to synthesize methyl 6-methoxypyridine-3-carboxylic acid esters. First, it can be obtained by esterification of 6-methoxypyridine-3-carboxylic acid and methanol under the catalysis of concentrated sulfuric acid. In this process, 6-methoxypyridine-3-carboxylic acid and excess methanol are co-placed in a reactor, concentrated sulfuric acid is slowly added, heated and stirred, and the reaction is carried out until a certain time. After the reaction is completed, it is neutralized, washed with water, and distilled to obtain a pure product.
Second, 6-halo-3-methoxypyridine can also be used as the starting material. First, it is carbonylated with carbon monoxide and methanol at a certain pressure and temperature in the presence of a palladium catalyst and suitable ligands. This reaction condition is quite critical, the pressure needs to be precisely controlled, and the temperature needs to be strictly maintained at a certain range in order to make the reaction proceed smoothly. After the reaction, the target product can also be obtained by separation and purification.
Furthermore, 6-hydroxypyridine-3-carboxylic acid is used as the starting material, and the hydroxyl group is first methylated to change to methoxy group, and then esterified with methanol under the action of an acidic catalyst. Methyl 6-methoxypyridine-3-carboxylic acid ester can also be synthesized. Each method has its own advantages and disadvantages, and it is necessary to weigh and choose according to the actual situation, such as the availability of raw materials, cost, and difficulty of reaction conditions.

Methyl-6-methoxypyridine-3-carboxylic acid ester, in the market, its price is geometric, and it is difficult to judge. This is due to the capriciousness of the market, and its price also varies with many reasons.
The price of various chemical substances in the past is related to raw materials. The abundance of raw materials directly affects the cost of this substance. If the raw materials required for the preparation of methyl-6-methoxypyridine-3-carboxylic acid ester are easily obtained and the price is flat, the price of this product may stabilize and decrease; on the contrary, if the raw materials are scarce and difficult to obtain, the price will rise.
Second, the clumsy process also has an impact. If the process is refined, the yield is high and the loss is small, the cost will drop, and the price will also drop; if the process is complicated and inefficient, the cost will be high, and the price will be difficult to lower.
Third, the supply and demand of the city is the most important. There are many who need it, but there are few who supply it, so the price will rise; if the supply exceeds the demand, the price will fall.
And where the market is located, it is also related to the price. Different states and regions have different taxes and transportation fees, which can make the price different.
Therefore, in order to know the exact price of methyl-6-methoxypyridine-3-carboxylate, it is necessary to carefully consider the current situation of raw materials, the state of the process, the shape of supply and demand, and the various reasons for the place, in order to obtain a more accurate number. However, the market conditions are ever-changing, and it is difficult to have a fixed price.

The manufacturer of methyl-6-methoxypyridine-3-carboxylic acid esters, although it is difficult to call it as many as stars in today's chemical market, there are also several well-known ones.
First of all, Sigma-Aldrich Company in the United States has a long-standing reputation. It has been working in the field of fine chemicals for many years and produces methyl-6-methoxypyridine-3-carboxylic acid esters with high quality, which are favored by many scientific research institutions and chemical companies. Germany's Merck (Merck) company, also in the production of chemical products, its products, with stable quality, occupy a place in the international market.
Looking at China, there are also many powerful manufacturers. For example, a chemical enterprise in Jiangsu, focusing on the production of heterocyclic compounds, the synthesis process of methyl-6-methoxypyridine-3-carboxylate, has studied deeply, and the products produced are not only supplied to many domestic manufacturers, but also exported overseas. There is also an enterprise in Shandong, with advanced production equipment and strict quality control system, the products produced are also well-known in the market. Their enterprises, either due to their exquisite craftsmanship or stable quality, have contributed to the production of methyl-6-methoxypyridine-3-carboxylic acid esters, contributing to the development of the chemical industry.
