To prepare 3% 2C3% 27-dibromo-5% 2C5% 27-bis (trimethylsilyl) -2% 2C2% 27-bipyridine, the method is as follows:
Take an appropriate amount of 2% 2C2% 27-bipyridine as the starting material, and add an appropriate amount of brominating reagent, such as liquid bromine or N-bromosuccinimide (NBS), to an appropriate reaction vessel. Taking liquid bromine as an example, the reaction needs to be carried out at a low temperature and in the presence of a suitable catalyst, such as iron powder or iron tribromide. The purpose of low temperature is to control the reaction rate and avoid excessive bromination. During the reaction process, the reaction progress can be closely monitored by means of thin-layer chromatography (TLC). When the reaction reaches a suitable level, a mixed system containing brominated products is obtained.
Then, the brominated products are silylated. The brominated products are placed in another reaction vessel with trimethylsilylation reagents, such as trimethylchlorosilane (TMSCl) and an appropriate amount of acid binding agent, such as triethylamine. This reaction is usually carried out in an organic solvent, such as anhydrous tetrahydrofuran (THF). The function of the acid binding agent is to neutralize the acid generated by the reaction, so that the reaction is carried out in the direction of generating the target product. The reaction temperature is adjusted according to the actual situation, usually at room temperature or when the reaction number is slightly heated. After the reaction is completed, it is separated and purified by methods such as column chromatography, using silica gel as a stationary phase, and eluted with an eluent in a suitable ratio to obtain a pure 3% 2C3% 27-dibromo-5% 2C5% 27-bis (trimethylsilyl) -2% 2C2% 27-bipyridine product. Each step of the reaction requires strict control of the reaction conditions and attention to the standard of operation to ensure the purity and yield of the product.

3% 2C3% 27 - dibromo - 5% 2C5% 27 - bis (trimethylsilyl) - 2% 2C2% 27 - bipyridine This substance has unique physicochemical properties. Its shape is either crystalline, its color is light, and its texture is relatively stable.
When it comes to the melting point, due to the interaction of groups in the molecular structure, its melting point is in a specific range, but the exact value needs to be determined by precise experiments. Its solubility may have a certain solubility in some organic solvents such as toluene and dichloromethane, and specific interactions can be formed between the Gain molecule and the solvent, such as van der Waals force, hydrogen bonding, etc.
In terms of chemical reactivity, the bromine atom in the molecule is active and can participate in many nucleophilic substitution reactions. In case of nucleophilic reagents, the bromine atom may be replaced to form a new organic compound, which makes the substance very important in the field of organic synthesis. Its bi (trimethylsilyl) structure endows the molecule with a certain spatial resistance, which affects its reactivity and selectivity. The bipyridine part, due to its conjugate structure, has a certain electronic effect, which affects the charge distribution and reactivity of the molecule as a whole, or can be used to construct materials with special electronic properties. And the substance may exhibit unique responses in physical environments such as light and electricity, providing possibilities for its application in the field of optoelectronic devices.

The price range of the "3%2C3%27-%E4%BA%8C%E6%BA%B4-5%2C5%27-%E5%8F%8C%28%E4%B8%89%E7%94%B2%E5%9F%BA%E7%A1%85%E5%9F%BA%29-2%2C2%27-%E8%81%94%E5%99%BB%E5%90%A9" item you are asking about is difficult to say in a word. The price is affected by many factors and is difficult to determine.
First, the quality of this item is related to the price. Those with excellent texture will be expensive; those with poor texture will be cheap. Second, the supply and demand of the city is also the key. If this item is in demand in the market, and the supply is scarce, the price will rise; if the supply exceeds the demand, the price may be downward. Third, the price varies depending on the place of production. The distance of origin and the abundance of resources can affect its cost, which in turn affects the selling price.
Furthermore, the market is changing rapidly, sometimes the price is high, sometimes the price is low, it is difficult to determine a fixed price range. Either due to changes in current events, or due to new things, the price will fluctuate. Therefore, to know the exact price range, you need to constantly observe the market dynamics, consult experts, or observe the prices of various trading platforms to obtain a more accurate number. Although it is difficult for me to tell you the price range directly, based on the above factors, we will be able to gradually understand the approximate price range.

Fu 3% 2C3% 27 - dicyano - 5% 2C5% 27 - bis (trimethylsilyl) - 2% 2C2% 27 - bipyridine, is also a chemical substance. Its storage conditions are crucial, related to the characteristics and stability of this substance.
First, it needs to be placed in a cool place. Cover a cool place with a low temperature, which can reduce the reaction caused by excessive temperature and avoid changes in its properties. If it is placed in a hot place, it may cause the movement of the internal structure of the substance, or the risk of decomposition and deterioration.
Second, drying is essential. Moisture easily reacts with many chemical substances. If this substance encounters water, or causes changes such as hydrolysis, its purity and quality will be damaged. Therefore, it is necessary to keep the storage place dry and moisture-free.
Third, sealed storage is indispensable. Sealing can isolate outside air from contact with oxygen, carbon dioxide and other components in the air. Due to oxygen or oxidation, carbon dioxide or acid and alkali changes are harmful to its quality.
Fourth, keep away from fire and heat sources. This substance may be flammable or unstable due to heat, and fire and heat sources are prone to fire or violent reactions, endangering safety.
Fifth, the storage place should be clearly marked. Mark its name, nature, hazards, etc., so that the person who takes it can see it at a glance, prevent misuse and ensure the safety of the operation. In this way, the chemical substance must be properly stored and used safely.
