2-Chloro-3-cyano-4-methoxypyridine is also an important compound in organic synthesis. There are several common synthesis methods.
First, pyridine is used as the starting material. Methoxylation of pyridine is performed first. The commonly used reagents are methanol and base. Under appropriate temperature and pressure, a methoxy group is introduced into the pyridine ring. Then, chlorine atoms are introduced at specific positions, and the chlorination reaction can be achieved by means of halogenating reagents such as chlorination agents in the presence of suitable catalysts. Finally, the introduction of 3-cyano is achieved through the cyanation step, using cyanide as the reagent. The steps of this route are clear, but the reaction conditions of each step need to be precisely controlled in order to obtain a higher yield.
Second, the pyridine derivative containing cyanogen and methoxyl is used as the raw material. First prepare the pyridine substrate containing methoxy and cyano, and then selectively introduce chlorine atoms at the specified position through halogenation reaction. The advantage of this approach is that the introduction of methoxy and cyanyl groups in the early stage or easier to operate. Halogenation is the key. Appropriate halogenating agent and reaction conditions need to be selected to ensure the selectivity of the introduction position of chlorine atoms and avoid side reactions.
Third, through the heterocyclic construction method. The pyridine ring is formed by multi-step cyclization reaction with small molecules containing nitrogen, oxygen, carbon and other atoms as raw materials, and chlorine, cyano, methoxy and other substituents are introduced during the cyclization process or subsequent steps. Although this method is complicated, it can start from simple raw materials and flexibly introduce each substituent according to the reaction design to provide more possibilities for synthesis. During the synthesis process, the conditions of each step of the reaction, such as temperature, solvent, catalyst, etc., have a great impact on the formation and purity of the product. Careful debugging and optimization are required to achieve the purpose of synthesizing the target product.

2-Chloro-3-cyano-4-methoxypyridine, the price of this product in the market is difficult to determine. The change in its price depends on various factors and is complicated.
First, it is related to the situation of supply and demand. If at a certain time, the industry has a strong demand for this product, but the supply is thin, the price will rise; conversely, if the supply exceeds the demand, the market will be flooded, and the price will fall. For example, if at a certain time, the pharmaceutical industry's demand for it surges to be used in the production of a new drug, and the manufacturer fails to respond in time, the price will be high.
Second, the price of raw materials is also a major factor. The preparation requires specific raw materials. If the price of raw materials rises, if a raw material encounters a disaster in the place of origin, the output decreases sharply, and the price becomes expensive, the cost of this compound will also increase, causing the price of the compound to rise in the market.
Third, the difficulty of preparation is related to the cost. If the preparation method is complicated, many rare reagents are required, or it takes a long time, energy consumption is high, and the cost will be high, its price in the market is also high.
Fourth, the state of market competition also has an impact. If there are many producers competing for profit, competing for market share, or the price will be reduced to promote; if only a few companies can make it, the price may be manipulated.
To sum up, in order to know the exact market price, a more accurate price can be obtained when the market supply and demand, raw material price changes, preparation costs and competition conditions are observed in real time.

2-Chloro-3-cyano-4-methoxypyridine is one of the organic compounds. Looking at its physical properties, under normal temperature and pressure, this substance is mostly in a solid state, and its melting point, boiling point and other characteristics are the key to judging its essence.
Melting point, the specific temperature at which the substance changes from solid to liquid. The melting point of 2-chloro-3-cyano-4-methoxypyridine varies depending on the intermolecular forces and the complexity of its structure. In its molecular structure, the existence of chlorine atoms, cyano groups and methoxy groups makes the intermolecular interactions complex.

Boiling point, the temperature at which the substance changes from liquid to gaseous. The boiling point of this compound is also dominated by intermolecular forces. Due to the characteristics of each group in the molecular structure, its boiling point may be higher. Due to the strong intermolecular interactions, more energy is required to vaporize it to overcome this force.
