First, in the field of medicinal chemistry, it is often used as a key intermediate. Gain aryl boronic acids can efficiently form carbon-carbon bonds with halogenated aromatics through the coupling reaction of Suzuki-Miyaura. Many drug molecules contain specific aryl-linked fragments in their structures. Through this reaction, fluorine-containing and acetyl-containing aryl structures can be precisely introduced, thereby providing a diverse library of compounds for drug development and facilitating the creation of new drugs. For example, when developing small molecule inhibitors for specific targets, 5-acetyl-2-fluorophenylboronic acid can be used as an important building block to build a core skeleton with biological activity through coupling reaction.
Second, in the field of materials science, it can be used to prepare functional organic materials. After Suzuki-Miyaura coupling reaction, it can be polymerized with other conjugated aromatic hydrocarbon monomers to construct polymers with unique photoelectric properties.

It is suitable for the preparation of organic Light Emitting Diodes (OLEDs), organic solar cells and other optoelectronic devices.
Third, in the field of total synthesis of natural products, 5-acetyl-2-fluorophenylboronic acid also plays a key role. The structure of natural products is often complex and unique, and the synthesis process requires precise functional group conversion and carbon-carbon bond construction. This reagent can be skillfully introduced into the target molecule through a coupling reaction to assist in the complete synthesis of complex natural products, providing a material basis for the study of the biological activity and mechanism of action of natural products.

To prepare 5-acetyl-2-fluorophenylboronic acid, the following method is often followed.
The starting material is 2-fluoroacetophenone, which is the basis of the reaction. First, 2-fluoroacetophenone is mixed into a suitable solvent, such as anhydrous tetrahydrofuran, to create a homogeneous reaction environment. After that, the system is cooled to a specific low temperature, such as -78 ° C, which is critical to the accuracy and selectivity of the subsequent reaction.
At this low temperature, n-butyl lithium is slowly added dropwise. N-butyl lithium is highly reactive. After contacting with 2-fluoroacetophenone, a lithium reaction occurs at a specific position in the benzene ring to form a lithium intermediate. This process requires close attention to the rate and temperature of the reaction to prevent overreaction or the growth of side reactions.
After the lithium reaction is completed, the system is maintained at a low temperature, and a borate ester, such as trimethyl borate, is added. The borate ester reacts rapidly with the lithium intermediate to form a boron-containing compound. This step of the reaction builds the structure of the boron atoms in the target product.
After the reaction is completed, the system is naturally warmed to room temperature to promote the reaction to further complete. Subsequently, the reaction mixture is acidified with a dilute acid, such as dilute hydrochloric acid. The purpose of acidification is to convert boron-containing compounds into 5-acetyl-2-fluorophenylboronic acid, while neutralizing the alkaline substances produced during the reaction.
After acidification, the product is extracted by extraction with a suitable organic solvent, such as ethyl acetate. After multiple extractions, the organic phases are combined and dried with anhydrous sodium sulfate to remove the moisture. Finally, the organic solvent is removed by vacuum distillation and the product is purified by column chromatography to obtain pure 5-acetyl-2-fluorophenylboronic acid.
In this synthesis method, each step requires fine control of the reaction conditions, such as temperature, reagent dosage and reaction time, to ensure high purity and high yield of the product.

5-Acetyl-2-fluorophenylboronic acid, its market price range is difficult to determine exactly, because the market is easy, the price is often affected by various factors.
First, the price of raw materials is the key end. The difficulty of obtaining the raw materials required for the synthesis of this compound and the fluctuation of prices have a deep impact on the pricing of finished products. If the raw materials are rare and rare, or their own prices vary depending on the season, origin, supply and demand, the price of 5-acetyl-2-fluorophenylboronic acid also fluctuates.
Second, the method of preparation is also important. To synthesize this product, the process is divided into complicated and simple, and the technology is different. If the delicate, complex and expensive method is adopted, the price will be high; and the simple and efficient process may make the price drop.
Third, the trend of supply and demand is common sense in the market. If the market demand for this compound is strong, but the supply is limited, it is like a rare product and the public is sought, the price will rise; conversely, if the supply exceeds the demand, in order to promote its sale, the price may drop.
Fourth, the differences between merchants cannot be ignored. Different merchants have different cost control, profit expectations, and business strategies, which also lead to different prices for the same product. In general, in the market of fine chemical products trading, the price of 5-acetyl-2-fluorophenylboronic acid per gram may be between tens of yuan and hundreds of yuan, but this is only a rough estimate. The actual price still needs to be determined according to the specific situation at that time.

5-Acetyl-2-fluorophenylboronic acid, when storing and transporting, many matters need to be paid attention to.
Its delicate nature is quite sensitive to the environment. When storing, find a cool, dry and well-ventilated place. This medicine is very easy to absorb moisture. If the ambient humidity exceeds, it may cause deliquescence and deterioration, and the efficacy will be lost. Therefore, it must be stored in a sealed device, and a desiccant can be placed inside to prevent moisture from invading.
Temperature is also the key. Extreme heat and cold are not suitable, and the left and right at room temperature are the best. If it is under high temperature, or causes a change in its chemical structure, the performance will not exist; if it is even colder, it is afraid that its physical form will change and affect the quality.
During transportation, shock resistance and anti-collision are the top priorities. The structure of this product is fragile, and external impact or packaging damage will cause damage, thereby damaging the medicine. The packaging material used should have excellent buffering ability to ensure its safety.
Furthermore, 5-acetyl-2-fluorophenylboronic acid may have certain chemical activity and cannot be stored and transported with oxidizing and reducing substances. The two meet or react violently, causing safety risks. And when handling, be sure to handle it with care, and the operator should also prepare protective equipment, such as gloves, goggles, etc., to prevent contact with the body.
Only in the storage and transportation sections, strictly abide by the regulations and pay attention to all details, in order to ensure the quality and safety of 5-acetyl-2-fluorophenylboronic acid, so that it can play its due effect where needed.
