3% 2C4% 2C5% 2C6 - Tetrachloropyridine - 2 - carboxylic acid, that is, 3,4,5,6 - tetrachloropyridine - 2 - carboxylic acid, its physical properties are as follows:
This compound is mostly in solid form at room temperature. From the appearance, it is often white to quasi-white crystalline powder, uniform and delicate. Its melting point is quite critical, generally in a specific temperature range. After many experiments, it is roughly between [X] ° C and [X] ° C. The melting point is relatively high, which indicates that the intermolecular force is strong and the structure is relatively stable.
In terms of solubility, it has very little solubility in water. Due to the large number of chlorine atoms in its molecular structure, it has strong hydrophobicity, making it difficult for water molecules to interact effectively with it. However, in some organic solvents, such as dichloromethane and acetone, it exhibits a certain solubility. In dichloromethane, it can be well dispersed and dissolved by virtue of the principle of similar miscibility, which is of great significance in the extraction and separation of organic synthesis.
Its density is also an important physical parameter. After precise measurement, it is about [X] g/cm ³, which makes it possible to achieve effective separation according to density differences when mixing with other substances or performing operations such as phase separation.
In addition, the compound has a certain vapor pressure, although the value is relatively small, but under high temperature or decompression environment, its vapor pressure will change, which in turn affects its volatilization performance. Under conventional laboratory environment and industrial production conditions, its volatilization degree is low, but under specific process requirements, its volatilization characteristics need to be considered.
In summary, these physical properties of 3,4,5,6-tetrachloropyridine-2-carboxylic acid have a non-negligible impact on its synthesis, application and treatment in chemical, pharmaceutical and other fields. Only by accurately grasping these properties can we be able to do it well in related operations.

The synthesis method of 3% 2C4% 2C5% 2C6-tetrachloropyridine-2-carboxylic acid, although the ancient book "Tiangong Kaiwu" does not contain this substance, it can be deduced according to the chemical synthesis idea of the ancient method.
To obtain this compound, first look at its structure, which contains a pyridine ring and many chlorinated and carboxyl groups.
One of the methods can be started from pyridine. The activity check point of the pyridine ring can be introduced into the chlorine atom by means of an electrophilic substitution reaction. The hydrogen atom on the pyridine ring is gradually replaced by a chlorine source such as chlorine gas or a chlorination reagent under the catalysis of a suitable catalyst such as a metal halide. < Br >
If pyridine and chlorine are catalyzed by ferric chloride before specific reaction conditions, the reaction temperature and time can be controlled, and chlorine atoms can be selectively introduced at specific positions in the pyridine ring. Repeat such reactions many times to achieve chlorination of the pyridine ring at positions 3, 4, 5, and 6.
When the chlorination of the pyridine ring is completed, the carboxyl group can be introduced. The Grignard reagent method can be used to react chloropyridine with magnesium to generate Grignard reagents, which are then reacted with carbon dioxide, and then acidified to obtain carboxyl groups.
Another method can be used to find pyridine derivatives containing carboxyl groups as starting materials, and chlorine atoms can be introduced at positions 3, 4, 5, and 6 of the pyridine ring by halogenation reaction. Halogenation is achieved under suitable reaction conditions with suitable halogenating reagents, such as chlorine-containing halogenating agents.
The control of reaction conditions, such as temperature, pressure, reaction time and the proportion of reactants, is crucial to the purity and yield of the product. After many tests and adjustment to the optimal reaction conditions, 3% 2C4% 2C5% 2C6-tetrachloropyridine-2-carboxylic acid can be efficiently synthesized.

I look at your question, but I am inquiring about the price of 3% 2C4% 2C5% 2C6 - Tetrachloropyridine - 2 - carboxylic acid in the market. However, the price of this chemical is not fixed, and it often changes due to multiple reasons.
First, the producers are different, and the prices are different. Large producers, depending on their scale and technical excellence, may be able to reduce costs, their prices may be low; small producers, on the contrary, their prices may be high.
Second, the amount is different, and the price is also different. The purchase volume is huge, and the seller often gives discounts, and the price is low; the purchase volume is small, and the price may be high.
Third, the supply and demand of the market is the main reason. < Br >
Fourth, the quality of high or low, also affects the price. High quality, the price must be higher than ordinary.
As far as I know, this product is in the market, the price per gram may be around tens of yuan to hundreds of yuan. If it is purchased in large quantities for industry, the price per ton may be tens of thousands of yuan. However, this is only a rough estimate. The actual price must be consulted with chemical raw material suppliers to obtain a definite number. Its price changes with the market, so it is necessary to inquire before purchase.

3% 2C4% 2C5% 2C6-tetrachloropyridine-2-carboxylic acid. The impact of this substance on the environment is quite important, which is related to the ecological balance and the safety of all living beings.
Looking at its chemistry, 3% 2C4% 2C5% 2C6-tetrachloropyridine-2-carboxylic acid is quite stable and is not easy to be rapidly decomposed in nature. If it enters the water body or accumulates in the bottom mud, it will gradually affect aquatic organisms. The photosynthesis of plankton, such as algae, is disturbed, causing growth to be inhibited. This change affects the whole body, affecting organisms that feed on algae, such as zooplankton, causing their quantity and distribution to change, and destroying the normal order of the aquatic ecological chain.
In the soil, 3% 2C4% 2C5% 2C6-tetrachloropyridine-2-carboxylic acid may affect the community of soil microorganisms. The activity of beneficial bacteria is damaged, and the soil nutrient cycle and organic matter decomposition are stunted. And it may be ingested by plant roots and accumulated in the body, which not only affects plant growth and development, but also causes short plants and reduced yields. It may also be transmitted to animals and humans through the food chain, threatening health.
In the atmosphere, although its direct volatilization may be limited, it will be dispersed through media such as dust or spread to distant places. After falling to the surface, it still affects the environment along the above path. Therefore, for this thing, we should be careful again and again, control its emissions from the source, develop efficient treatment methods, protect the environment and ecology, and ensure the harmonious coexistence of all things.
