To prepare methyl 2-amino-4-chlorobenzoate, there are various methods. One is to start with 4-chlorobenzoic acid, first place it in a reactor with methanol, add sulfuric acid as a catalyst, and heat it up to boiling and reflux. This is a classic esterification method, and sulfuric acid can promote the reaction of the two to improve the yield of ester. However, sulfuric acid is strong and corrosive, and it needs to be handled with caution. The reaction is as follows: 4-chlorobenzoic acid + methanol $\ xrightarrow [] {sulfuric acid} $4-chlorobenzoate methyl ester.
Then, with methyl 4-chlorobenzoate as material, add an appropriate amount of mixed acid of nitric acid and sulfuric acid in the reactor, control the temperature in a suitable range, and carry out nitrification reaction to obtain methyl 4-chloro-2-nitrobenzoate. This step requires strict temperature control to prevent side reactions. Its formula is: methyl 4-chlorobenzoate + mixed acid $\ xrightarrow [] {} $4-chloro-2-nitrobenzoate. At the end of
, methyl 4-chloro-2-nitrobenzoate is catalyzed by hydrogenation of 4-chloro-2-nitrobenzoate in an alcohol solvent at room temperature and pressure, and the nitro group is then converted into an amino group to obtain methyl 2-amino-4-chlorobenzoate. This step is clear, but you need to pay attention to safety in the hydrogenation step, and hydrogen is easy to ignite and explode.
There are other ways as well. If 2-nitro-4-chlorobenzoic acid is used as the starting material, it is first esterified with methanol, and then hydrogenated to reduce the nitro group to an amino group as before. All methods have advantages and disadvantages, and need to be selected according to the actual situation, such as the availability of raw materials, cost, equipment, etc., in order to efficiently obtain methyl 2-amino-4-chlorobenzoate.

Methyl 2-% hydroxy-4-methoxybenzoate is an organic compound. It has the following physical and chemical properties:
Looking at its appearance, it often shows a white to light yellow crystalline powder at room temperature, with a fine texture and a fine luster visible in sunlight.
When it comes to the melting point, it is about 110 ° C - 112 ° C. In this temperature range, the substance gradually melts from a solid state to a liquid state, which is a key property in the identification and purification of this compound.
In terms of boiling point, under specific pressure conditions, it can reach a certain value, but the exact boiling point will vary slightly depending on the experimental conditions. This property is related to its stability and volatility in high temperature environments. < Br >
Solubility is also an important property. It is slightly soluble in water, because water is a highly polar solvent, and although the compound contains ester groups derived from hydroxyl and carboxyl groups, the overall polarity is limited, so it is difficult to dissolve in water. However, in organic solvents such as ethanol and ether, the solubility is quite good. The polarity and molecular structure of the organic solvent are compatible with the compound, which is conducive to molecular interaction and promotes its dissolution.
Stability is relatively stable under general conditions. When encountering strong acids and bases, ester groups are prone to hydrolysis. In an acidic environment, hydrolysis produces 2-hydroxy-4-methoxybenzoic acid and methanol; under alkaline conditions, hydrolysis is more rapid and thorough, and the products are corresponding carboxylate and methanol. In addition, long-term light or high temperature environment may also cause decomposition or other chemical reactions, affecting its quality and structure.
This compound has important applications in medicine, fragrance, cosmetics and other fields due to its unique physical and chemical properties. In the field of medicine, or can be used as an intermediate in drug synthesis; in the fragrance industry, because of its special structure or endowing products with a unique aroma; in cosmetics, or because of some of its characteristics, it plays a stabilizing and preservative role.

In today's world, the business situation is mixed, and the market price is impermanent. However, the price of methyl 2-amino-4-chlorobenzoate in the market also has its approximate range.
In the past, the production of this product, the process is complicated, and the materials used are rare, so its price is high. However, as the years go by, craftsmen study hard, the skills are new, the production method is gradually becoming simpler, and the materials used are gradually easy to obtain, so the price tends to drop.
Looking at the cities, the price range often changes according to the quality and the urgency of supply and demand. If its quality is pure, flawless, and suitable for the market, the price will be very high. The price per catty is roughly between a few hundred gold and a thousand gold. If the quality is slightly inferior, or the supply and demand between the cities is unbalanced, and the supply exceeds the demand, the price may be discounted, and the price per catty may be below a few hundred gold.
Then business is like a flow, changing rapidly. The abundance of the place of origin, the change of government orders, and the stability of the current situation can all determine the price. In order to know the exact price, you must visit the cities and ask experts in real time to obtain it. Although there is an approximate price range, if you want to be accurate, you should not be limited to the previous statement, and you must study it at any time.

Methyl 2-% hydroxy-4-methoxybenzoate is a very important organic compound, which is widely used in many fields such as medicine, cosmetics, food, etc. Its storage conditions are crucial, which is related to the quality and stability of this substance.
According to the concept contained in "Tiangong Kaiwu" and the method of preservation of various substances by the ancients, combined with current scientific understanding, methyl 2-hydroxy-4-methoxybenzoate should be stored in a cool, dry and well-ventilated place. A cool environment can maintain the temperature at a low level to avoid the molecular movement of the substance due to excessive temperature, which can lead to chemical reactions and deterioration. In general, the storage temperature should be kept between 15 ° C and 25 ° C.
Dry conditions are also indispensable. Because methyl 2-hydroxy-4-methoxybenzoate may have a certain water absorption, if the ambient humidity is high, it is easy to absorb water vapor, which may not only cause deliquescence, but also may induce reactions such as hydrolysis and destroy its chemical structure. Therefore, the humidity of the storage place should be controlled at 40% to 60%.
Good ventilation can disperse volatile gases that may accumulate in time, avoid danger caused by excessive local concentration, and can maintain the fresh air in the storage environment, reducing the possibility of contact with harmful gases.
In addition, methyl 2-hydroxy-4-methoxybenzoate should be stored in a sealed container. One can prevent it from reacting with oxygen, carbon dioxide and other gases in the air, and the other can avoid dust, impurities and other mixing to ensure its purity. Storage containers should be made of glass or specific plastic materials, because their chemical properties are relatively stable and not easy to react with the substance.
And storage should be kept away from fire sources, heat sources and strong oxidants. Although methyl 2-hydroxy-4-methoxybenzoate is not extremely flammable, it may still be dangerous in case of open flames and hot topics. Strong oxidants may react violently with it, causing it to deteriorate or causing safety accidents.
