The synthesis method of 6- (methoxycarbonyl) pyridine-3-carboxylic acid, although the ancient book "Tiangong Kaiwu" does not contain this specific synthesis method, it can be analyzed from the usual method of chemical synthesis.
First, pyridine is used as the starting material. Pyridine can be halogenated to introduce halogen atoms at appropriate positions, such as halogen at the 3-position or 6-position of pyridine, and bromine or chlorine is commonly used. Halogenated pyridine can be obtained by heating the reaction between bromine and pyridine under the catalysis of appropriate catalysts such as iron powder. After that, through cyanidation, the halogen atom is replaced by a cyano group with a cyanide reagent such as sodium cyanide to obtain cyanopyridine. After hydrolysis, the cyanyl group is hydrolyzed into a carboxyl group, and pyridine-3,6-dicarboxylic acid can be obtained by heating with a strong acid such as sulfuric acid. Finally, one of the carboxylic groups is esterified, and methanol and pyridine-3,6-dicarboxylic acid are heated and refluxed under the catalysis of concentrated sulfuric acid to obtain 6- (methoxycarbonyl) pyridine-3-carboxylic acid.
The second, can also be suitably substituted for benzene as a raw material. First, pyridine rings are formed by cyclization reaction, such as cyclization with isophenylenediamine and ethyl acetoacetate under appropriate conditions to form pyridine derivatives. Then the substituent on the pyridine ring is modified, and the suitable substituent is converted into a carboxyl group by oxidation, and then the esterification reaction is also carried out. With methanol and suitable catalysts such as p-toluenesulfonic acid, the target product 6- (methoxycarbonyl) pyridine-3 -carboxylic acid can be obtained.
Although there is no modern chemical synthesis method in "Tiangong Kaiji", today's chemical synthesis relies on the accumulation of chemical knowledge and the development of science and technology through the ages to obtain a variety of effective synthesis methods for the chemical industry and scientific research.

6- (methoxycarbonyl) pyridine-3-carboxylic acid, this is an organic compound. Its physical properties are quite critical, and it is widely used in the chemical and pharmaceutical fields.
Let's talk about the appearance first. At room temperature and pressure, 6- (methoxycarbonyl) pyridine-3-carboxylic acid is often white to light yellow crystalline powder, with fine texture, just like the snow that falls in the early winter, pure and uniform. This form is conducive to storage and transportation, because it has good stability and is not easy to change the state due to slight external vibration or environmental changes.
In terms of melting point, it has been accurately determined to be between 140 and 145 ° C. The characteristic of melting point is like the "temperature code" of a substance. When the ambient temperature rises to this range, the compound will quietly transform from solid to liquid, and the intermolecular forces will rearrange and combine. This characteristic is of great significance in the process of material purification and identification. Its purity can be judged by melting point measurement. If the purity is high, the melting point range is narrow and close to the theoretical value; if it contains impurities, the melting point decreases and the range becomes wider.
Solubility is also an important physical property. This compound is slightly soluble in water, just like a leaf floating on the surface of a lake, with only a little integration into it. However, it has good solubility in common organic solvents such as dichloromethane and ethanol, just like a fish entering water, and can closely blend with solvent molecules. Such solubility characteristics are very useful in organic synthesis experiments. Scientists can choose a suitable solvent to dissolve the compound according to the needs of the reaction, so that it can participate in various chemical reactions and promote the smooth progress of the reaction.
In addition, 6- (methoxycarbonyl) pyridine-3-carboxylic acid has a certain degree of hygroscopicity. Like a sponge placed in the air, it will absorb moisture from the surrounding environment, which requires storage in a dry environment and sealed storage to prevent moisture absorption from affecting its chemical properties and quality, and ensure that it can play a stable role in subsequent use.

6 - (methoxycarbonyl) pyridine-3 -carboxylic acid, this substance is in the market, the prospect can not be lightly cut off. In the field of Guanfu Chemical Industry, the demand for fine chemicals is constantly increasing. This compound may be involved in the genus of medicine and pesticides, and it is widely used.
In the way of medicine, it can be used as an intermediate to make all kinds of good medicines and treat human diseases. In today's world, the pharmaceutical industry is booming, and the demand for delicate intermediates is increasingly ardent. If this acid can help to become a special medicine, it will be favored by pharmaceutical companies, and the capacity of the market may be widely expanded.
As for the pesticide industry, new compounds are often the basis for creating high-efficiency and low-toxicity pesticides. If this acid is used in pesticide synthesis, it has unique properties and can be used to make the best agent for agricultural protection and pest control, then the agrochemical market can also open a convenient door for it.
However, there are various obstacles to its entry into the market. The synthesis method needs to be simple, efficient and environmentally friendly. If it is difficult to prepare and expensive, it will be difficult to be accepted by the market. And when new chemical products enter the market, they must follow the rules and go through many tests to prove their safety.
Even though there are challenges, opportunities coexist. With the development of science and technology, if we can overcome its problems and give full play to its strengths, 6- (methoxycarbonyl) pyridine-3-carboxylic acids may emerge in the chemical market, gaining a place and promising prospects.
