If you start with a compound containing a specific structure, under suitable reaction conditions, you can meet the reagent with a specific functional group.
can cause the starting compound to interact with the acylating reagent. This acylating reagent needs to be carefully selected, and its structure and reactivity are exquisite. After acylation, a specific acyl group can be introduced. This step requires attention to the choice of reaction temperature and solvent. If the temperature is too high or too low, it may affect the process and yield of the reaction; the polarity and solubility of the solvent also have a great impact on the reaction. It is necessary to choose a suitable solvent so that the reactants can be fully mixed and contacted to facilitate the reaction.
Then, the obtained acylated product is reacted with an amination reagent. The basic and nucleophilic properties of this amination reagent are related to the location and efficiency of amino group introduction. Control the reaction conditions, such as reaction duration and temperature changes, etc., so that the amination reaction can occur smoothly, and the amino group is successfully introduced.
As for the ester-forming step, take the product after amination and carry out the esterification reaction with the alcohol compound under catalytic conditions. The type and dosage of the catalyst need to be precisely controlled. If the catalyst activity is too high or too low, the reaction may go astray. At the same time, the pH, moisture content and other factors of the reaction system also need to be paid close attention. Too much water or the esterification reaction will proceed in reverse, which will affect the formation of esters.
After this series of reactions, the conditions of each step of the reaction should be adjusted in sequence, and the operation should be careful, or the ethyl ester of 4-yl-2-amino can be obtained. However, in the way of chemical synthesis, the subtleties are all about success or failure, and each step needs to be done carefully to obtain the ideal product.

What is the market price of 4-iodine-2-methoxy-3-pyridyl formaldehyde?
One evening, a person from Jia asked the crowd, "I want to know what the market price of methoxybenzaldehyde is?" Hearing this, everyone pondered.
There are wise men, knowledgeable and knowledgeable, and the price of all kinds of things in Suxiao City should be said: "The market price of methoxybenzaldehyde is not fixed, and it often changes due to changes in time, place, and supply and demand. If you are in a prosperous year, everything is sufficient, and the product is also abundant, and the price may be slightly lower; if you are in a desolate age, everything is difficult, and if it is rare, the price will be high.
And the distance of the place is also related to the price. If it is produced nearby, its transportation will be economical, and the price will be flat; if it comes from a distance, involving mountains and rivers, and passing through long distances, the cost of transportation will be high, and the price will be high.
As for the state of supply and demand, it is especially important. Those who want it are many, but those who supply it are few, the price will be higher; if the supply exceeds the demand, and the stock of goods is difficult to sell, the price will drop.
Recently, the price of this product in the city, either because of the high cost of raw materials and the increase in labor costs, has risen slightly compared with the past. However, looking at the cities, the price per catty is also around the hundred gold, or there may be minor differences, depending on the situation in different places. "
Jia people heard it, nodded and praised it as good, knowing that the market price of methoxybenzaldehyde has its own reasons. When the supply and demand conditions of the time and place are carefully observed, the exact price can be obtained.
What are the storage conditions for 4-iodo-2-methoxy-3-pyridyl formaldehyde?
In the world described in "Tiangong Kaiwu", the storage of methyl ether depends on its properties. Methyl ether is flammable and volatile, and the most important thing to hide is to avoid open flames.
If you want to hide methyl ether, you should choose a cool place. If the methyl ether is heated, the vapor pressure will rise, and the container will be vulnerable and cause leakage. Therefore, hiding in the shade can reduce this problem. Such as the back of the house and the depth of the cellar, it is suitable.
Furthermore, the utensil used should be sturdy and airtight. Methyl ether is volatile, and if the container has a gap, it must be scattered outside. It should be stored in copper and iron utensil, because its texture is firm and tight, it can prevent leakage. The mouth of the device must also be tightly sealed to prevent gas leakage.
Also, the place where the methyl ether is hidden should be well ventilated. If there is a slight leakage, the wind can disperse, so that it will not gather in one place and explode in case of fire. And do not mix with other things, especially avoid strong oxidants, kindles, etc., to prevent accidents.
The utensils where the methyl ether is hidden should always be checked for density and damage. If the utensils have rust or cracks, they should be replaced quickly to avoid leakage and disaster. In short, the hidden methyl ether needs to be cautious. According to its characteristics, it should be kept cool, airtight, ventilated, and away from kindling debris and regular inspection regulations to keep it safe.
