The chemical synthesis method of 3-methyl-4-hydroxypyridine has been around for a long time, and has been honed over the years, and is now mature and diverse.
The first method is derived from the conversion of pyridine compounds. Take a suitable pyridine derivative, under specific conditions, first introduce methyl. Suitable methylating reagents, such as iodomethane, can be selected under the catalysis of alkali to methylate at a specific position on the pyridine ring. Then, the hydroxylation step is performed. At this time, a specific oxidant and catalyst can be combined to hydroxylate at a specific position on the pyridine ring, and finally 3-methyl-4-hydroxypyridine can be obtained. < Br >
Second, a compound containing a specific functional group is used as the starting material to construct a pyridine ring through a multi-step reaction. For example, a compound with a suitable carbon chain and functional group is selected, and the pyridine ring is formed first through condensation, cyclization and other reactions. During the reaction process, the reaction conditions and the order of reagents are precisely controlled, so that the 3-methyl-4-hydroxyl structure is naturally formed on the pyridine ring. This process requires careful consideration of the reaction conditions at each step, and temperature, solvent, catalyst, etc. are all key elements.
Third, there is also an exploration of biosynthetic pathways. Using the catalytic properties of specific microorganisms or enzymes, starting with relatively simple substrates, the target product is gradually synthesized by enzymatic reaction in a mild biological environment. Although this approach started a little later, it has gradually become more important in the academic community due to its advantages such as green and high efficiency.
There are many methods for synthesizing 3-methyl-4-hydroxypyridine, each with its own advantages and disadvantages. Chemical synthesis methods require fine operation, and biosynthesis methods have yet to be developed and perfected. However, they are all effective ways to obtain this important compound. With the advance of science and technology, the synthesis method will become more delicate and efficient.

3-Methyl-4-hydroxypyridine is in the market, and its price range is difficult to determine. This is due to many reasons, resulting in its price fluctuations.
First, the supply and demand situation is the key. If there are many people, but the supply is thin, the price will rise; on the contrary, if the supply exceeds the demand, the price may fall. In the chemical, pharmaceutical and other industries, if the need for 3-methyl-4-hydroxypyridine is greatly increased, and the producer does not respond to it, the price will rise.
Second, the manufacturing cost is also a major factor. The price of raw materials, energy costs, labor costs, etc., all affect its cost. If the price of raw materials rises, or the cost can be high, resulting in an increase in manufacturing capital, its price in the market will also increase accordingly.
Third, the competition situation of the market is involved. If there are many of these, the price may decline in order to compete for the market; if there are few players, it has the tendency to monopolize, and the price may be controllable and high.
Fourth, policies and regulations, international market conditions, etc. also have an impact. Changes in policies, such as stricter environmental regulations, increase costs for producers, and prices also change. Turbulence in the international market, such as changes in exchange rates, trade barriers, etc., may cause fluctuations in prices.
Overall, the market price of 3-methyl-4-hydroxypyridine can range from a few hundred yuan per kilogram to more than a thousand yuan. It is difficult to determine the exact value, and it varies with the above factors.
