What are 5-Bromo-2-cyanobenzotrifluoride synthesis methods?

The synthesis method of 5-bromo-2-cyanotrifluorotoluene has been studied by many people in the past. One method is to start with 2-cyano-5-nitrotrifluorotoluene. After reduction, 2-cyano-5-aminotrifluorotoluene is obtained. After that, it is combined with hydrobromic acid and sodium nitrite to carry out diazotization reaction, and then treated with hypophosphoric acid to obtain the target product. In the process, the reduction step, or the combination of iron powder and hydrochloric acid, or the method of catalytic hydrogenation, is selected according to the actual needs.

There are also those who use 2-methyl-5-bromotrifluorotoluene as the starting material. First, the methyl is oxidized to a carboxyl group with a mild oxidizing agent, such as potassium permanganate, to obtain 5-bromo-2-carboxylic trifluorotoluene, and then reacts with dichlorosulfoxide to form an acid chloride, and then reacts with cuprous cyanide to obtain 5-bromo-2-cyanotrifluorotoluene through a variant of the Sandmeier reaction. In this path, the oxidation conditions are very controlled, and if they are too strong, other groups will be damaged.

In addition, 3-bromo-4- (trifluoromethyl) aniline is used as a base. It is first reacted with cyanate to form a cyano-substituted amide. After being treated with a dehydrating agent such as phosphorus pentoxide, it is dehydrated to form a nitrile, that is, 5-bromo-2-cyanotrifluorotoluene. In the meantime, the steps of amide dehydration should pay attention to the reaction temperature and time to avoid side reactions.

All kinds of synthesis methods have their own advantages and disadvantages. When implementing, make a careful choice based on factors such as the availability of raw materials, cost considerations, difficulty of reaction, and high or low yield.

5-Bromo-2-cyanobenzotrifluoride What are the precautions during storage and transportation?

5-Bromo-2-cyanotrifluorotoluene is a chemical substance commonly used in organic synthesis. During storage and transportation, many matters must be paid attention to to ensure safety.

First storage, this substance should be stored in a cool, dry and well-ventilated place. Because it is more sensitive to heat and high temperature can easily cause it to decompose and deteriorate, it should be avoided from heat sources and fire sources. The temperature of the storage place should be controlled at a lower range to ensure its chemical stability. And it should be stored separately from oxidizing agents, acids, bases and other substances to prevent dangerous chemical reactions. Due to its certain toxicity and corrosiveness, storage containers must be made of corrosion-resistant materials and must be tightly sealed to prevent leakage.

As for transportation, extreme caution is also required. Before transportation, the container should be strictly inspected to ensure that there is no damage and no risk of leakage. During transportation, proper protective measures must be taken to avoid collisions and vibrations to prevent damage to the container. Transportation vehicles should also be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. Transportation personnel should be professionally trained to be familiar with the characteristics of this substance and emergency treatment methods. If a leak occurs during transportation, immediate and effective measures should be taken to evacuate surrounding personnel to prevent the spread of pollution and report to relevant departments in a timely manner.

In conclusion, the storage and transportation of 5-bromo-2-cyanotrifluorotoluene is related to safety and quality, and must not be taken lightly. It is necessary to strictly follow relevant norms and requirements to ensure the safety of personnel and the environment from pollution.

What is the market price of 5-Bromo-2-cyanobenzotrifluoride?

The market value of 5-bromo-2-cyanotrifluorotoluene is determined due to various factors involved. This compound is widely used in the field of chemical raw materials, and it is often used in the field of chemical raw materials, synthesis, etc., and the demand side is different. It will affect the quality of its own products.

If it is used in research and development, due to the high quality requirements of the product, its price will remain high. Due to the need for refined raw materials for synthesis, there is no room for difference pools, and the cost of production is high.

In the field of chemical raw materials, the cost requirement is slightly lower, but the wave of market demand will also affect it. If the demand for the first phase of production increases sharply, the demand for 5-bromo-2-cyanotrifluorotoluene also increases, and the price may be on the rise; conversely, if the demand is low, the price will not be depressed.

Furthermore, the cost of supply should not be ignored. The production capacity, production capacity, and quality of raw material supply of this compound are all high. If raw materials are scarce or the production cost is large, the supply price will be limited, and the price will be pushed up by it; conversely, if there are many factories and production profits, and the supply is sufficient, the price may be reduced.

In the past, the market was not like it, and the price was not prosperous. In the early years, due to technical limitations, the cost of production was high, and the market was high. With technological innovation, the efficiency of production has been improved, the cost has been slightly reduced, and the price has also declined. However, recently, due to the lack of insurance policies, some households have been limited, and some raw materials have been limited, and their market value has not changed.








<, in order to know the market of 5-bromo-2-cyanotrifluorotoluene, it is necessary to target the market, supply and demand, raw material market, policy law and other factors, and it is appropriate to add a price to the chemical raw material trading platform, industry or business, in order to obtain the price of the phase.
