To prepare 2-cyanogen-3-hydroxy-4-methylpyridine, there are various methods.
First, start with the corresponding pyridine derivative and go through the cyanidation method. Take the pyridine containing the appropriate substituent first, and react with the cyanide reagent such as potassium cyanide and sodium cyanide at a suitable temperature and in the presence of a catalyst. During the reaction, it is necessary to strictly control the reaction conditions, such as temperature, pH, etc., to promote the accurate access of the cyanyl group to the predetermined position to form the cyanide-containing pyridine intermediate. Next, the hydroxylation reaction is carried out. Suitable hydroxylation reagents can be selected, such as alkali metal hydroxides, etc., in a specific reaction system, the hydroxyl group can be introduced at a specific position of the intermediate, and the final target product is 2-cyanogen-3-hydroxy-4-methylpyridine.
Second, through a multi-step condensation reaction. Take small molecule compounds containing functional groups such as methyl and aldehyde groups as raw materials, such as methylaldehyde and nitrogen-containing compounds. First, the nitrogen-containing compound and the compound with suitable functional groups undergo a condensation reaction to construct the prototype of the pyridine ring. In this step, a suitable catalyst and reaction solvent need to be selected to guide the reaction in the desired direction. Later, on the pyridine ring, cyano and hydroxyl groups are introduced in sequence through a specific reaction sequence. For example, the cyanide group is first introduced by cyanation reaction, and then the hydroxyl group is added by hydroxylation reaction, and after each step of the reaction, the separation and purification technique needs to be used to remove impurities and increase the purity of the product.
Third, the method of biosynthesis. Microorganisms or enzymes with specific catalytic activities can be found, and specific substrates can be used as starting materials. Microorganisms or enzymes can catalyze substrates under mild conditions through a series of biochemical reactions to gradually synthesize 2-cyano- 3-hydroxy-4-methylpyridine. This process requires fine adjustment of the environment for culturing microorganisms, such as temperature, pH, nutrients, etc., to maintain the activity of microorganisms or enzymes and promote the synthesis reaction. And the biosynthetic method often has the advantages of high selectivity and environmental friendliness, but there are also shortcomings such as long reaction cycle and difficult product separation, which still need to be studied to improve it.

2-% -3-methyl-4-methylpyridine, this material has multi-physical properties. Under normal conditions, it is generally in the shape of a solid, and it is not easy to change its shape by itself.
























< b The boiling temperature also depends on a specific temperature, such as [Y] ° C, at this temperature, the 2-% 3-methyl-4-methylpyridine of the liquid will be intensified and turned into a steaming liter.
In terms of solubility, it has a certain solubility in water and can be partially dissolved, so that the aqueous solution has a slight special taste, just like a faint grassy aroma. Among the soluble solutions, such as ethanol, acetone, etc., its solubility is better, and it can be well miscible to form a uniform solution.
In terms of density, 2-%-3-@-@yl-4-methylpyridine has a specific value, relative to water, and the specific gravity is [Z], so that it is mixed in water, depending on the density difference. If it is put into water, it may either float on the water surface or sink on the bottom according to its density characteristics, depending on the difference in its density.
In addition, 2-% 3-yl-4-methylpyridine has certain properties. Under normal conditions, a small amount of steaming will be released slowly, and the steaming will be highly pungent. However, in the steaming environment with slightly higher temperatures, or in the respiratory tract, it will cause micro-irritation.

2-% -3-methyl-4-methylpentanoic acid is one of the most common compounds. Its chemical properties are specific, and I will describe them here.
First of all, this compound contains an alkyl group, and the alkyl group has an alkyl water group, so it may have a certain solubility in water. Because the oxygen atom in the alkyl group is very poor, the alkyl water can form alkyl, so that this substance can be dispersed in the water environment.
Furthermore, the alkyl group can be polymerized and reactive. It can be esterified and reactive. In case of carboxylic acid, under acid catalysis and addition of alkyl, the carboxyl group of the alkyl group of the carboxylic acid can be combined with water to form an ester compound. This reactive group is often used in the synthesis of alkyl, and can be used for various esters. It is useful in the synthesis of fragrances and other fields.
The molecule still contains methyl group, which is the carrier group. Due to its donor effect, the density of the sub-cloud of other functionalities in the molecule is affected. For example, it can increase the density of the sub-cloud on the near carbon, changing its anti-reactivity.
And the atom in this compound, the different positions of the compound are affected by the different environments, and its activity is also different. The carbon phase of the carbon phase is affected by the atom effect of the alkyl group, and the active phase is high. In some anti-reactive components, it can be replaced by other groups.
In addition, the carbon properties of this compound also play a role. The shortness and branching of carbon molecules affect their physical properties such as melting and boiling, density, etc., and in the reaction, carbon emissions also affect the reaction path and rate. Therefore, the chemical properties of 2-% 3-yl-4-methylvaleric acid are enriched, and their various functional functions interact with carbon, resulting in multiple reaction characteristics.

Today, there are 2-cyanogen-3-hydroxy-4-methylpyridine, and I would like to know its price range on the market. This is a specific compound in the field of fine chemicals, and its price often varies due to changes in quality, purity, and market supply and demand.
If it is ordinary purity, it is about hundreds of yuan per kilogram. Those who cover such purity are mostly used in general chemical synthesis experiments. The demand is wide, and the production scale is relatively large. Therefore, the cost is controllable and the price is close to the people.
However, if high purity is pursued, such as for high-end fields such as pharmaceutical research and development, the price will skyrocket. The preparation of high-purity products requires complex processes, multiple precision purification processes, strict requirements on raw materials and equipment, and limited output. Its price may reach thousands of yuan per kilogram, or even higher.
Furthermore, the market supply and demand relationship is also the key. When the demand is strong and the supply is insufficient, even for ordinary purity products, the price will rise; on the contrary, if the market is saturated and the supply is excessive, the price may drop.
Factors such as fluctuations in raw material prices and regional differences in manufacturers will all affect the final selling price. Therefore, in order to know the exact price range, it is necessary to consult various suppliers in detail and synthesize multiple information to obtain it.
