The synthesis method of 2-chloro-5- (2-fluorophenyl) -1H-pyrrole-3-formonitrile has been used by many parties throughout the ages.
First, fluorobenzene derivatives are used as starting materials. First, fluorobenzene is substituted with a specific reagent, and a suitable group is introduced at a specific position in the benzene ring. This step requires precise control of the reaction conditions, such as temperature, catalyst type and dosage. If the temperature is too high, side reactions will occur frequently, and if it is too low, the reaction will be delayed. Subsequently, the obtained product is fused with the precursor compound containing the pyrrole structure and cyclized to form a pyrrole ring. In this process, the choice of reaction solvent is very critical, and different solvents have a great impact on the reaction rate and product purity.
Second, start from the parent of pyrrole-3-formonitrile. First, chlorination of pyrrole-3-formonitrile is carried out, so that chlorine atoms are selectively attached to specific positions. This reaction requires attention to the activity and dosage of chlorinated reagents to avoid excessive chlorination. Then, 2-fluorophenyl is introduced into the 5 position of the pyrrole ring through a coupling reaction. In the coupling reaction, the choice of catalyst and ligand is extremely important, which determine the selectivity and efficiency of the reaction.
Third, by means of multi-step tandem reaction method. With simple and easy-to-obtain basic raw materials, in the same reaction system, through careful design of reaction sequence and conditions, each step of the reaction occurs in sequence and directly generates the target product. Although this method can simplify the operation process, it requires extremely high control of the reaction conditions. It is necessary to precisely control factors such as temperature, pH and reactant ratio in order to make each step of the reaction proceed smoothly and improve the yield of the product.
The above synthesis methods have their own advantages and disadvantages. In practical application, it is necessary to carefully choose the appropriate method according to the availability of raw materials, cost considerations, product purity requirements and many other factors.

2-Chloro-5- (2-fluorophenyl) -1H-pyrrole-3-formonitrile is an organic chemical. When storing and transporting, the following things should be noted:
First, the storage environment must be dry and cool. This compound is susceptible to water vapor, which can cause adverse reactions such as hydrolysis, which can damage its quality. A cool place can slow down its possible natural reaction rate and maintain its chemical stability. For example, it needs to be placed in a dryer and stored in a warehouse with a temperature of 5 to 25 degrees Celsius.
Second, this compound is quite sensitive to light. Light may cause photochemical reactions to cause structural changes or decomposition. Therefore, it should be stored in brown bottles or opaque containers to avoid direct sunlight or strong light.
Third, when transporting, be sure to ensure that the packaging is tight. If there is an omission in the packaging, it will not only leak or cause compound loss, but also endanger the transporter and the surrounding environment. Packaging materials should have good sealing and impact resistance to prevent package damage due to bumps and collisions during transportation.
Fourth, because it is a chemical, transportation and storage must strictly follow relevant regulations and standards. Relevant personnel must be professionally trained and familiar with its characteristics and emergency treatment methods. In the event of an accident such as a leak, it can respond quickly and correctly, such as collecting the leak with an appropriate adsorbent to prevent its spread.
Fifth, the storage place should be kept away from fire sources and oxidants. This compound may be at risk of combustion or explosion in case of open flame or strong oxidants. The storage area should also be kept at a safe distance from fire sources and oxidant substances, and be equipped with corresponding fire protection facilities.

I think what you are asking is about the market price of "2-chloro-5- (2-fluorophenyl) -1H-pyrrole-3-formonitrile". However, the price of this chemical substance often changes for various reasons.
First, the price of raw materials has a great impact. If the price of chlorine, fluorobenzene and pyrrole required for the synthesis of this substance varies depending on supply and demand, origin and season, the price of this product will also fluctuate.
Second, the difficulty of preparation is related to cost. If the synthesis method requires complicated steps, special equipment, expensive catalysts, or huge energy consumption, the cost will rise, and the price will also be high.
Third, the supply and demand situation of the market is the key. If many industries, such as medicine, materials, etc., have strong demand for this material, but limited supply, the price will increase; conversely, if the demand is low and the supply is sufficient, the price may decrease.
Fourth, the size and brand of the manufacturer also play a role. Large factories can reduce costs by virtue of scale effect, and the price may be competitive; while well-known brands may have slightly higher prices due to quality assurance.
However, we cannot state the exact price directly, because the market is changing rapidly and the price varies from place to place. For details, you can consult chemical raw material suppliers, chemical product trading platforms, or professionals in related industries, who can tell you a more accurate price based on the current market conditions.
