The synthesis method of 2-chloro-4-cyanopyridine has been explored by many scholars in the past, and now the number of common ones is mentioned.
First, pyridine is used as the initial raw material. Shilling pyridine interacts with an appropriate halogenating agent, such as chlorine gas or a chlorine-containing reagent, under suitable reaction conditions, a halogenation reaction occurs at a specific position on the pyridine ring, and chlorine atoms are introduced to form chloropyridine-containing derivatives. Then, through the cyanidation step, cyanide reagents (such as sodium cyanide, etc.) react with it, so that the corresponding check point on the pyridine ring is introduced into the cyano group, and finally 2-chloro-4-cyanopyridine is obtained. In this process, the conditions of the halogenation reaction, such as reaction temperature, reaction time, and the amount of halogenating agent, need to be carefully regulated to make the chlorine atom fall precisely at the second position of the pyridine ring; the cyanidation reaction also needs to pay attention to the pH of the reaction environment, the stability of the reaction system and other factors to ensure the smooth introduction of cyanyl groups into the fourth position.
Second, a specific pyridine derivative is used as the starting material. If the starting pyridine ring already has some functional groups that can be converted into chlorine atoms and cyanos, the synthesis of the target product can be achieved through a series of functional group conversion reactions. For example, a group that can be halogenated and is easy to cyanide on the pyridine ring is selectively halogenated, converted into a chlorine atom, and then converted into a cyanide group by a cyanidation step under specific reaction conditions, thereby synthesizing 2-chloro-4-cyanopyridine. This path requires precise design of the structure of the starting pyridine derivative, and in-depth consideration of the selectivity and yield of each step of the conversion reaction to ensure that the reaction proceeds in the expected direction.
Third, the reaction is catalyzed by transition metals. A substrate containing a pyridine structure is coupled with a chlorine-containing reagent and a cyanide-containing reagent in the presence of a transition metal catalyst (such as a metal complex such as palladium and copper). Transition metal catalysts can effectively promote the reaction process, improve the reaction efficiency and selectivity. This method requires high reaction conditions. The selection of catalysts, the design of ligands, and the screening of reaction solvents all have a significant impact on the success or failure of the reaction and the purity and yield of the product. During the reaction, parameters such as catalyst dosage, reaction temperature and reaction time need to be strictly controlled to achieve the purpose of efficient synthesis of 2-chloro-4-cyanopyridine.

2-Chloro-4-cyanopyridine, this material has unique physical properties. Looking at its properties, it is mostly white to light yellow crystalline powder under normal conditions, uniform and delicate, with a subtle luster visible under light, as if it contains a mysterious charm.
When it comes to the melting point, it is about 116-120 ° C. This temperature limit is quite critical, just like a checkpoint. When the outside temperature rises to this range, 2-chloro-4-cyanopyridine will gradually melt from the solid state, transforming from a regular crystalline state to a flowing liquid state, just like ice and snow meeting warm sun, quietly changing its shape.
Its solubility is also an important physical property. In organic solvents, such as common methanol, ethanol, acetone, etc., all show good solubility. Just like fish entering water, they can closely blend with these solvents and disperse them evenly. However, the solubility in water is very small, and the water is too cold to accommodate this substance. The two are like two parallel lines, and it is difficult to have too much intersection.
Furthermore, its stability is also worthy of attention. Under conventional environmental conditions, if there is no extreme temperature, humidity or strong oxidants, reducing agents and other external factors, 2-chloro-4-cyanopyridine can maintain its own structural stability, and its properties are not easily changed. It is like a calm person who sticks to himself in the hustle and bustle of the world.

2-Chloro-4-cyanopyridine is an important raw material in organic synthesis. It has unique chemical properties and plays a key role in many chemical reactions.
This compound contains chlorine atoms and cyano groups, which give it specific reactivity. Chlorine atoms are active and can participate in nucleophilic substitution reactions. Nucleophilic agents can attack carbon atoms connected to chlorine atoms, and chlorine atoms leave to form new organic compounds. This reaction is widely used to introduce various functional groups and expand molecular structures.
Cyanyl groups also have special chemical behaviors. Cyanyl groups can be hydrolyzed to form carboxyl groups. Under suitable conditions, they react with water and catalysts and are converted into carboxyl groups through a series of reactions. This property is often used in the synthesis of compounds containing carboxyl groups, which is of great significance in the field of pharmaceutical synthesis and materials science.
Furthermore, the cyanyl group can be reduced to an amino group. With a specific reducing agent, the triple bond in the cyanyl group is added to the hydrogen atom and gradually converted into an amino group. This provides an effective way for the synthesis of amino-containing compounds, which are indispensable in the preparation of bioactive molecules and organic functional materials.
2-chloro-4-cyanopyridine Due to the existence of chlorine atoms and cyanyl groups, it exhibits a variety of chemical reactivity and is widely used in the field of organic synthesis, laying the foundation for the creation of complex organic compounds with unique functions.

In today's world, business conditions are ever-changing, and it is difficult to determine the price of 2-chloro-4-cyanopyridine in the market. The range of its price is often influenced by various factors, such as the abundance of raw materials, the difficulty of production, the amount of demand, and the trade situation.
In the past, the price of such chemical materials was mostly based on market supply and demand. If the raw materials are sufficient, the production process is mature, and there are few people who need them, the price will decline; conversely, if the raw materials are scarce, the production is difficult, and the parties compete for purchases, the price will rise.
Looking at the past market conditions, the price of 2-chloro-4-cyanopyridine can reach tens of gold per kilogram at low times, and hundreds of gold per kilogram at high times. However, these are all examples in the past. Today's market is changing rapidly, and it is absolutely difficult to determine the current price.
If you want to know the current price range, you should never consult a merchant specializing in this industry, or check the recent market reports and trade information. They can often know the latest price, and can give people an accurate number. And the market is constantly changing, even if the exact price is obtained at a moment, it may be different soon. Therefore, always pay attention to the dynamics of the market, is a good way to get a price.
