The synthesis of 2-hydroxy-4-mercaptopyridine is an interesting and challenging topic in the field of organic synthesis. The following is a detailed description of the steps and methods for its synthesis.
First, the commonly used starting material is 2-hydroxy pyridine. This compound can be obtained through a variety of mature organic reaction pathways. First, a halogen atom is introduced into the 4-position of the pyridine ring with a suitable halogenating agent, such as bromine or chlorine, to form 4-halo-2-hydroxy pyridine. This step requires fine regulation of reaction conditions, such as temperature, reaction duration, and reagent ratio. If the temperature is too high or the reaction is too long, it may cause excessive halogenation or other side reactions, which will damage the purity and yield of the product.
In the second case, 4-halo-2-hydroxypyridine is converted to 2-hydroxy-4-mercaptopyridine. This step usually uses thiohydrogenation reagents, such as sodium hydrosulfide (NaHS) or thiourea. Taking sodium hydrosulfide as an example, in a suitable solvent, such as alcohols or polar aprotic solvents, the halogen atoms can be replaced by thiol groups by heating and stirring. The choice of solvent is crucial, and its polarity and solubility will affect the reaction rate and product distribution.
Furthermore, during the reaction, in order to ensure the smooth progress of the reaction and improve the purity of the product, it is often necessary to add a catalyst or acid binding agent. Some transition metal catalysts or phase transfer catalysts can accelerate the substitution reaction of halogen atoms. The acid binding agent can neutralize the acid generated by the reaction and promote the reaction equilibrium to move in the direction of the product.
After the synthesis is completed, the product needs to be separated and purified. Common methods include recrystallization, column chromatography, etc. Recrystallization requires a suitable solvent to dissolve the product in a hot solvent, and pure crystals are precipitated after cooling. Column chromatography is based on the difference in the distribution coefficient between the product and the impurities in the stationary phase and the mobile phase to achieve separation.
In summary, the synthesis of 2-hydroxy-4-mercaptopyridine requires strict control of the reaction conditions at each step and fine operation to obtain high-purity products to meet the needs of scientific research and industrial production.

I have not heard the exact price of 2-hydroxy-4-mercaptopyridine in the market. The price of this compound may vary due to differences in quality, purity, supply and purchase quantity. If this product was unknown in the world of "Tiangong Kaiwu", it would be difficult to have this fine chemical product. However, at this time, the inquiry price is equivalent to the supplier of chemical raw materials and the sales platform of chemical reagents. As the saying goes, the price of bulk purchase is excellent, and the price of small retail is high. For details, you can consult merchants and compare the prices quoted by each company to get an approximate price range. The price may fluctuate according to market supply and demand. If the supply is sufficient, the price will stabilize or decrease, and if the demand is strong and the supply is tight, the price will rise. If you want to get a definite price, it is a good policy to inquire in person.
