What are 5-Amino-2-Fluorobenzotrifluoride synthesis methods?
The synthesis method of 5-amino-2-fluoro-trifluorotoluene has been known for a long time, and it is described in this article.
First, fluoro-containing nitrobenzene is used as the starting material. First, fluoro-nitrobenzene containing an appropriate substituent is reacted with a trifluoromethylation reagent. This reaction needs to be carried out in a suitable solvent, such as an aprotic polar solvent, and the reaction temperature and time should be controlled. Common trifluoromethylation reagents, such as trifluoromethyl magnesium halide, etc. After this reaction, trifluoromethyl can be introduced to obtain a nitrobenzene derivative containing trifluoromethyl. Then, the derivative undergoes a reduction reaction, and the commonly used reducing agents such as iron/hydrochloric acid system, hydrogen/palladium carbon catalyst, etc. Under suitable conditions, the nitro group can be reduced to an amino group to obtain 5-amino-2-fluorotrifluorotoluene.
Second, the halogenated aromatic hydrocarbon is used as the starting material. The benzene derivative containing fluorine and halogen is selected, and the trifluoromethylation reagent is first used to react to construct the halogenated benzene containing trifluoromethyl. Then the halogen atom is replaced by an amination reagent. The Ullmann reaction or the like can be used in the presence of a copper catalyst and a base to react the halogen with ammonia or an amine compound to achieve amination and finally obtain the target product.
Third, starting from the benzoic acid derivative. The benzoic acid is first subjected to a series of substitution reactions such as fluorination and trifluoromethylation, and fluorine and trifluoromethyl are introduced at a specific position in the benzene ring. Then, the carboxyl group is converted into an amino group. The carboxyl group can be first converted into an acid chloride, then reacted with ammonia to form an amide, and finally degraded by Hoffman, so that the amide is converted into an amine with one less carbon atom, that is, 5-amino-2-fluorotrifluorotoluene.
All synthesis methods have their own advantages and disadvantages, and must be carefully selected according to factors such as actual demand, raw material availability and cost.
5-Amino-2-Fluorobenzotrifluoride What are the precautions during storage and transportation?
5-Amino-2-fluorotrifluorotoluene is an organic compound. When storing and transporting, the following matters should be paid attention to:
One is the storage environment. This compound should be placed in a cool, dry and well-ventilated place. Do not expose to high temperature and humid environment. Due to high temperature or accelerated volatilization, moisture may cause chemical reactions and cause it to deteriorate. The warehouse temperature should be controlled within a specific range, such as not exceeding 30 ° C, and the relative humidity should not exceed 75%. And it should be kept away from fires and heat sources. It is strictly forbidden to have open flames or smoking in the storage area.
The second is about packaging. The packaging must be tight to prevent leakage. It is commonly used in sealed containers, and the material of the container must be compatible with the compound and will not chemically react with it. The name of the chemical, hazard characteristics, emergency treatment methods and other information should be clearly marked on the outside of the package for identification and disposal.
The third is transportation requirements. The transportation process must follow relevant regulations and standards. Transportation vehicles should be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. This compound cannot be mixed with oxidants, acids, alkalis, etc., because it may react violently with these substances and cause danger. During transportation, ensure that the container does not leak, collapse, fall or damage. During driving, drivers and escorts need to pay close attention to the condition of the goods, and once any abnormalities are detected, they should be properly handled immediately.
The fourth is personnel protection. When storing and transporting personnel, wear appropriate protective equipment, such as protective glasses, gas masks, acid and alkali-resistant gloves, etc., to prevent exposure to or inhalation of the compound and damage to health. At the same time, the workplace should be equipped with eye washers and showers. If you come into contact accidentally, you can deal with it in time.
What is the market price range for 5-Amino-2-Fluorobenzotrifluoride?
5-Amino-2-fluorotrifluorotoluene, this product is in the market, and its price range is difficult to determine. Because of the market price, it is often influenced by various factors.
The first is the raw material. The abundance and price of raw materials have a great impact on the cost of 5-amino-2-fluorotrifluorotoluene. If raw materials are abundant and cheap, the cost of production will drop, and the market price may also decrease; on the contrary, if raw materials are rare, the cost will rise, and the price will also rise.
The other is supply and demand. If the market demands 5-amino-2-fluorotrifluorotoluene, but the supply is limited, the price will rise; if the supply exceeds the demand, the merchant will sell its goods or reduce the price, and the price will decline.
The complexity of the process is also relevant. If the preparation method is complicated, multiple processes, special reagents or equipment are required, the cost will be high, and the price will be high; if the process is simple, the cost can be controllable, and the price may be close to the people.
In addition, policies and regulations, international situation, transportation costs, etc., can disturb its market price. Therefore, in order to determine the market price range of 5-amino-2-fluorotrifluorotoluene, it is necessary to observe the market dynamics in real time and analyze various factors. Generally speaking, its price fluctuates widely at different times and at different merchants, ranging from hundreds of yuan per kilogram to thousands of yuan. It is difficult to determine a fixed price range.
