2% 2C6-difluoro-3-hydroxypyridine is a key compound in the field of organic synthesis. There are various synthesis methods, as follows:
First, pyridine is used as the starting material. Shilling pyridine reacts with halogenating reagents under suitable conditions to introduce halogen atoms, which can be chlorine, bromine, etc. Subsequently, by means of nucleophilic substitution reactions, halogen atoms are replaced by fluorine reagents to achieve the introduction of fluorine atoms. As for the introduction of hydroxyl groups, specific substituents can be hydrolyzed under basic conditions or reacted with hydroxylating reagents. For example, the halogenated pyridine is reacted with potassium fluoride in a polar solvent under high temperature and pressure to introduce fluorine atoms; then, through the basic hydrolysis step, the halogenated atoms are replaced by hydroxyl groups, thereby generating 2% 2C6-difluoro-3-hydroxypyridine.
Second, the strategy of using fluorine-containing blocks to construct pyridine rings. Suitable fluorine-containing compounds can be selected, and compounds containing nitrogen and carbonyl can be reacted in multiple steps to construct pyridine rings. For example, fluorine-containing β-dicarbonyl compounds and ammonia or amine compounds are formed by a series of reactions such as condensation and cyclization under the action of acidic or basic catalysts. At the same time, through rational design of reaction steps and reagents, the fluorine atom and hydroxyl group are in the desired position, that is, 2% 2C6-position and 3-position.
Third, the reaction catalyzed by transition metals. Transition metal catalysts such as palladium and copper can efficiently catalyze the formation of various carbon-heteroatomic bonds. Using suitable halogenated aromatics or halogenated olefins as substrates, with fluorine-containing reagents and hydroxyl-containing reagents, under the action of transition metal catalysts and ligands, 2% 2C6-difluoro-3-hydroxypyridine can be precisely synthesized through multi-step catalytic reaction. For example, palladium-catalyzed cross-coupling reaction can couple halogenated pyridine derivatives with fluoroborates to introduce fluorine atoms; and then through subsequent reactions, hydroxyl groups are introduced at the 3-position.
The above synthesis methods have their own advantages and disadvantages. In practical application, the most suitable synthesis path should be carefully selected according to the comprehensive consideration of many factors such as raw material availability, reaction conditions, cost and yield.

Today, there are 2,6-difluoro-3-hydroxypyridine, and the price in the market is difficult to determine. This is a product used in fine chemicals, and its price is determined by many reasons.
First, the price of raw materials is also. If the raw material required for its preparation is easy and cheap, the price of this product may not be high; on the contrary, if the raw material is rare and difficult to find, its price must be high.
Second, the method of preparation. If the preparation method is simple and easy to implement, and requires less labor and material resources, the cost will decrease and the price will also decrease; if the preparation method is difficult, special tools and agents will be used, and the time will be long, the cost will increase, and the price will also rise.
Furthermore, the demand of the market. If at some time, many businesses need this product, the market is in high demand, but the supply is not enough, and the price will rise; if the demand is few, the supply will exceed the demand, and the price will fall.
Also, there are differences between producers. Different producers have different costs due to differences in scale, technology, and management, and their pricing is also different. Most of the well-known factories focus on quality, and the products are excellent, and the price may be slightly higher. However, there are also small factories that compete for the market and sell them at low prices.
Therefore, in order to know the exact price of 2,6-difluoro-3-hydroxypyridine, we can obtain a more accurate number when we carefully consider the price of raw materials, the method of preparation, market supply and demand, and the situation of producers.

2% 2C6-difluoro-3-hydroxypyridine is a very rare pharmaceutical intermediate, and its storage conditions are crucial to the quality and stability of this substance.
This substance should be stored in a cool, dry and well-ventilated place. A cool environment can slow down the rate of chemical reactions that may occur. If the temperature is too high, or its molecular activity is greatly increased, it will cause undesirable changes such as decomposition and polymerization, which will damage its structure and properties. Generally speaking, the storage temperature should be controlled between 2-8 ° C. This temperature range can effectively maintain its chemical stability.
Dry environment is also indispensable. Because 2% 2C6-difluoro-3-hydroxypyridine or has a certain water absorption, if the ambient humidity is too high, it may absorb water vapor, causing its own deliquescence, and even react with water to change its chemical composition. Therefore, where it is stored, the relative humidity should be kept at 40% - 60%.
Good ventilation can disperse harmful gases that may be volatilized in time, and avoid potential safety hazards caused by high local concentrations. At the same time, it needs to be stored separately from oxidants, acids, bases and other substances. Because of its active chemical properties, contact with the above substances may cause violent chemical reactions, endangering safety. < Br >
Storage containers are also particular about using corrosion-resistant materials, such as glass or specific plastic containers, and must be well sealed to prevent the intrusion of air, water vapor, etc.
Only by strictly following these storage conditions can we ensure the quality and performance of 2% 2C6-difluoro-3-hydroxypyridine during storage, providing a reliable raw material basis for subsequent production and application.
