Guanfu 5-hydroxy- 2 - (trihydroxymethyl) glutaric acid, the stability of its chemical properties, is related to the direction of many reactions, which is the key to chemical exploration.
In this compound, hydroxyl groups coexist with methyl and other functional groups, and hydroxyl groups are active and can participate in many reactions, such as esterification reactions, which can combine with acids to form esters and water. However, it is also easily oxidized. In a specific oxidation environment, hydroxyl groups or carbonyl groups are changed.
The trihydroxymethyl part, due to its special structure, causes molecules to have a certain steric barrier. This barrier may affect the rate and way of reaction with others. When the steric resistance is large, the effective rate of intermolecular collision is reduced, and the reaction may require more severe conditions.
Furthermore, the main chain structure of glutaric acid also affects its properties. Its chain length is moderate, and the distribution of electron clouds on the chain affects the activity of functional groups. And the skeleton of glutaric acid imparts a certain degree of flexibility to the molecule, which may play a key role in some reactions, such as intramolecular reactions.
Overall, the chemical properties of 5-hydroxy- 2 - (trihydroxymethyl) glutaric acid are not a simple superposition of the properties of a single functional group due to the interaction of various parts of the structure. Its stability is not absolute, and it may exhibit different chemical behaviors under different temperatures, pH, catalysts, etc. In a mild environment, if there is no strong oxidizing agent, strong acid and alkali, etc., it may be able to maintain relative stability; however, under suitable reaction conditions, each functional group will actively participate in the reaction according to its inherent chemical characteristics, and the stability will also change. Therefore, in order to determine the stability of its chemical properties, it is necessary to observe the reaction conditions carefully and cannot be generalized.

The synthesis method of 5-alkynyl-2- (trialkynyl methyl) pyridine can be done according to several ancient methods and wonderful methods.
First, pyridine is used as the base, and the alkynyl group is first introduced. Choose pyridine as the starting material, and add an appropriate amount of solvent, such as tetrahydrofuran, to stabilize its state in a suitable reaction vessel. Then add a strong base, such as n-butyllithium, with its strong alkalinity, take away the hydrogen at a specific position of pyridine, so that pyridine has nucleophilic properties. Then add alkynyl-containing halogenated hydrocarbons, such as propargyl bromide, and the two go together to undergo nucleophilic substitution reaction. In this way, the alkynyl group is connected to the pyridine ring to obtain the pyridine intermediate
Second, on the basis of the above intermediates, trialkynyl methyl is introduced. Taking the intermediate as the raw material, tetrahydrofuran is still used as the solvent, and then a strong base is added for activation. Then add a reagent containing trialkynyl methyl, such as (trialkynyl methyl) halides, and after nucleophilic substitution, the trialkynyl methyl is connected to a specific position of pyridine, and finally 5-alkynyl-2- (trialkynyl methyl) pyridine is obtained.
There is another way to construct the trialkynyl methyl part first, and then connect it to pyridine. Starting with an appropriate alkyne, after a multi-step reaction, an active intermediate containing trialkynyl methyl is first prepared. At the same time, the pyridine is activated to make the specific position on the pyridine ring have nucleophilic or electrophilic activity. Then the two are mixed in a suitable reaction system, and by nucleophilic addition or electrophilic substitution, trialkynyl methyl is connected to pyridine, and the target product can also be obtained.
In addition, the method of transition metal catalysis can be considered. Select a suitable transition metal catalyst, such as palladium catalyst. With a substrate containing alkynyl groups and pyridine, in the presence of suitable ligands, bases and solvents, under the catalysis of transition metals, through a coupling reaction, each group is precisely connected to synthesize 5-alkynyl-2 - (trialkynyl methyl) pyridine with high efficiency. Each of these methods has its own advantages and disadvantages, and it is necessary to consider the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, the purity of the product, etc., and choose the optimal method for synthesis.

What is the price of this item in the market today? I should answer it in the form of "Tiangong Kaiwu".
The price of various things in the world often changes with many factors, and it cannot be covered in one word. The price of this item of Wujin bis (Sanjin methyl) is related to the place used, the amount required, and the time of production.
If it is gathered in workshops and used widely, the price may be higher if it is more. If it is located in a remote place, the need is few, and the price may be lower.
When the seasons change, in the place where this product is produced, if there is a lot of production, the price will fall; if there is a disaster year, the output will be scarce, and the price will be expensive.
Furthermore, the quality of this product is also the main reason. Those who are of high quality will have a higher price than usual. As "Tiangong Kaiwu" said, all things are the same, and those with high quality will be demanded by everyone, and the price will also increase.
There are also rules of the trade road, and the people who sell and walk around will also change the price. Long-distance transshipment costs a lot, and its price will increase; if the production and sales are similar, the cost will not be much, and the price will be stable.
In summary, the price of wujin bis (triazinomethyl) in the market, or due to time, place, quality, and trade routes, fluctuates and is difficult to determine. It is necessary to observe carefully in the city to know the exact price.
