The solubility of 2,2 '-bipyridine-4,4' -di-tert-butyl dicarboxylate is related to many chemical manipulations and is an important characteristic. This substance has different solubility in common organic solvents. It is slightly soluble in alcoholic solvents such as methanol and ethanol. The polarity of alcohols interacts with the partial structure of the substance, but its ester group and bipyridine structure limit its solubility, so the solubility is not good.
In halogenated hydrocarbon solvents such as dichloromethane and chloroform, the solubility is slightly better. The moderate polarity of halogenated hydrocarbons is in good agreement with the structure of the substance, which can disperse some molecules. However, due to its large molecule and complex structure, it cannot be infinitely miscible.
As for water, the solubility of this substance is extremely low. Because its molecules contain hydrophobic bipyridine rings and ester groups, which are contrary to the strong polarity of water, it is difficult to form effective interactions, so it is almost insoluble in water.
In organic solvents such as N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), the solubility is quite good. The two have strong polarity and good solvation ability, and can form various interactions with 2,2 '-bipyridine-4,4' -di-tert-butyl dicarboxylate, such as hydrogen bonds, van der Waals forces, etc., to promote uniform dispersion and achieve good solubility.
In conclusion, 2,2 '-bipyridine-4,4' -di-tert-butyl dicarboxylate has excellent solubility in polar organic solvents such as DMF and DMSO, and has certain solubility in alcohols and halogenated hydrocarbons, but it is difficult to dissolve in water. This characteristic needs to be carefully considered in chemical synthesis, separation and purification, etc., in order to make good use of it.

First, find a cool and dry place. This medicine is afraid of moisture and heat. If it is placed in a warm and humid place, its medicinal properties may change, and it is easy to cause the container to rust and damage, causing the medicine to leak. Gu Yun: "It is dry to nourish it, and cool to protect it, so as to protect its properties."
Second, the storage place must be strong and well sealed. This medicine is very toxic. Once it leaks, it will harm the surroundings, so the container must be solid and tightly sealed to prevent it from escaping. If it is ancient to hide poison, it must be heavily covered with thick porcelain and sealed with wax.
Third, the storage place should be guarded by special personnel, and it is strictly forbidden for unrelated people to approach. This is to prevent accidental touch and misuse, resulting in tragedies. When a special person is set up on rotation, strictly guard the surrounding area, and those who trespass will be severely punished.
Fourth, the mark must be clear and eye-catching. In the storage place, the words "highly toxic" are written in a large book, so that people can see the danger from a distance, in case they accidentally approach.
In short, the storage of 2%2C2%27-%E8%81%94%E5%96%B9%E5%95%89-4%2C4%27-%E4%BA%8C%E7%94%B2%E9%85%B8%E4%BA%8C%E9%92%A0%E7%9B%90 is related to human life and safety, and must not be taken lightly. It must be done with caution according to the above methods.

The synthesis method of 2,2 '-bipyridine-4,4' -dimethyl dicarboxylate is quite important. Common methods include those that use 2,2 '-bipyridine as the starting material. First, 2,2' -bipyridine is reacted under appropriate reaction conditions to make it react with reagents that can introduce carboxyl methyl ester groups. If it can be reacted with halogenated carboxylic acid methyl ester in a suitable catalyst and solvent environment. In this process, the catalyst can be selected with certain metal salts, and the solvent can be selected according to the reaction requirements. Appropriate organic solvents are selected to help the reaction proceed smoothly. < Br >
Or first modify 2,2 '-bipyridine, introduce a group that is easy to convert into carboxyl methyl ester at a specific position, and then undergo a series of reactions to achieve the purpose of converting the group into carboxyl methyl ester. The reaction steps involved in this should be carefully designed according to chemical principles and past experience.
There are also those who start from other related compounds and construct the structure of 2,2' -bipyridine through multi-step reactions, and at the same time introduce a dimethyl dicarboxylate group at the 4,4 '-position. This path may require more fine reaction regulation, and the control of reaction conditions is quite high. Each step of the reaction requires attention to factors such as the proportion of reactants, reaction temperature, and reaction time, so that the synthesis reaction can proceed according to the expected direction and improve the yield and purity of the target product 2,2 '-bipyridine-4,4' -dimethyl dicarboxylate.
