4-Amino-2,3-dichloropyridine, an important organic compound, is widely used in medicine, pesticides and other fields. As for its market price range, it is difficult to determine exactly, because it is determined by many factors.
First, the fluctuation of raw material prices has a significant impact. If the basic raw materials required for the preparation of 4-amino-2,3-dichloropyridine, such as specific chloropyridine, amines, etc., the price fluctuates with market supply and demand, changes in origin, international situation, etc., the cost of 4-amino-2,3-dichloropyridine will fluctuate, which will affect the selling price.
Second, the difference in production technology is also related to price. Sophisticated and efficient production technology can reduce energy consumption, yield, impurities, cost control, and price may be competitive; on the contrary, outdated and complicated processes have high costs and different prices.
Third, the market supply and demand situation is a key factor. If the demand for new drugs containing this compound surges in pharmaceutical research and development, or products with this as a key intermediate in the pesticide field sell well, the supply is insufficient and the price will rise; if the market is saturated and the competition is fierce, the price may stabilize or even decline.
Fourth, product purity and quality level have a significant impact. High purity and high quality products are used in high-end medicine, electronics and other fields, and the price is high; ordinary purity products are used in general industrial production, and the price is relatively low.
According to past market conditions and industry information, the price may range from hundreds to thousands of yuan per kilogram. However, the market is unpredictable, and real-time prices need to be consulted with relevant chemical product suppliers and trading platforms to obtain accurate figures.

The production process of 4-amino-2,3-dichloropyridine cannot be generalized in terms of its complexity. The production of this compound often involves multi-step reactions, and each step needs to be carefully controlled to ensure product quality and yield.
The selection of initial raw materials is extremely critical, and high purity is required to avoid reaction deviation caused by impurities. Usually pyridine is used as the starting material, and chlorine atoms are introduced at a specific position in the pyridine ring through halogenation reaction. This step of reaction conditions is severe, and the temperature, reaction time, and proportion of reactants must be precisely regulated. The choice of reagents and catalysts used in halogenation is also important, and different combinations have a significant impact on the reaction rate and selectivity.
After the introduction of chlorine atoms, the amination reaction is carried out. This process may use an amination reagent to replace the chlorine atom with an amino group under specific solvents and reaction conditions. This step also requires attention to the reaction conditions, such as temperature, pressure, reaction time, etc., to ensure that the amination reaction is sufficient and reduce the occurrence of side reactions.
In the reaction process, monitoring and control means are indispensable. Modern analytical technologies such as gas chromatography and liquid chromatography can monitor the reaction process in real time, helping operators to adjust the reaction parameters in a timely manner. Separation and purification steps are also complicated. The product may contain impurities such as unreacted raw materials and by-products. It needs to be purified by extraction, distillation, crystallization and other methods to obtain high-purity 4-amino-2,3-dichloropyridine.
However, the simplicity of the production process varies with different production scales and technical levels. Large-scale industrial production, although advanced equipment and automated control systems can be used to improve production efficiency and simplify the operation process, the cost of upfront equipment investment and process optimization is high. Small-scale laboratory production, although highly flexible, requires more manual operations, and is limited by equipment and technology, and the process may be more complicated.
Overall, the production process of 4-amino-2,3-dichloropyridine has a certain complexity, and it is necessary to comprehensively consider various factors such as raw materials, reaction conditions, monitoring methods, separation and purification, in order to achieve the purpose of efficient and stable production.

4-Amino-2,3-dichloropyridine is one of the organic compounds and is widely used in medicine, pesticides and other fields. Its Quality Standards involve quite a lot, as detailed below.
First of all, in terms of appearance, 4-amino-2,3-dichloropyridine should be in a white to light yellow crystalline powder, which is pure and has no impurities visible to the naked eye. This is a visual representation of quality, which is related to the initial impression and preliminary quality judgment of the product.
Times and content, this is the key indicator. Generally speaking, its content needs to reach more than 98.0%, and even up to 99.0% and higher. The high content indicates that the product has good purity and contains less impurities. It can more accurately exert its chemical characteristics in subsequent applications, reduce side reactions caused by impurities, and ensure stable and reliable product performance. The melting point of 4-amino-2,3-dichloropyridine is also an important consideration. The melting point of 4-amino-2,3-dichloropyridine is about 155-159 ° C. The determination of the melting point can help to determine the purity and crystal structure of the product. If the melting point deviates from this range, it may suggest that the product is mixed with impurities, which affects its physical and chemical properties. The moisture content of
must be strictly controlled, generally should not exceed 0.5%. Excessive moisture may cause adverse reactions such as hydrolysis of the product, which affects its chemical stability and storage life.
As for the relevant substances, they need to be detected and controlled by precise analytical methods such as high performance liquid chromatography. The content of specific impurities shall not exceed the established limit, which is designed to ensure the quality and safety of the product and prevent the potential harm of impurities to human health or the environment.
In summary, the Quality Standards of 4-amino-2,3-dichloropyridine have clear and strict regulations from appearance to specific indicators to ensure the quality and performance of their applications in different fields.

4-Amino-2,3-dichloropyridine is a chemical substance, and its storage conditions are crucial for safety and quality. When this substance is stored, the first environment is dry. Because of its certain hygroscopicity, if the storage environment is humid, it is easy to absorb water vapor, causing its properties to change, or affecting the effect of chemical reactions. Therefore, it should be stored in a dry and ventilated warehouse, away from water sources and steam pipes and other places prone to moisture.
Temperature control is also critical. It should be stored in a cool environment, generally 2-8 ° C. High temperature can easily damage the stability of the substance, or cause adverse reactions such as decomposition and polymerization, which reduce its purity and activity.
Furthermore, care should be taken to avoid light. 4-Amino-2,3-dichloropyridine is sensitive to light. Long-term light exposure may promote photochemical reactions and change its chemical structure and properties. It should be stored in dark containers such as brown bottles, or in a place without direct light.
At the same time, it should be stored separately from oxidants, acids, alkalis and other substances. Because of its active chemical properties, it comes into contact with the above substances, or reacts violently, leading to safety accidents. When storing, there should be obvious intervals between different types of chemicals, and clear labels should be affixed.
In addition, the storage place should be equipped with corresponding fire protection equipment and leakage emergency treatment equipment. In case of leakage or fire and other accidents, we can take quick response measures to reduce losses. The handling process must be handled lightly to avoid damage to the packaging container and material leakage.
