To prepare 3-hydroxy-4- (trifluoromethyl) pyridine, there are many methods, each with its own advantages and disadvantages. The selection of the method is required according to the needs, and the difficulty, yield, cost, etc. are considered. The common preparation methods are as follows:
First, the compound containing the pyridine structure is used as the starting material, and the halogen atom is introduced into the pyridine ring by halogenation reaction, and then the nucleophilic substitution reaction is carried out to replace the reagent containing the trifluoromethyl group with the halogen atom, and then the hydroxyl group is introduced through suitable reaction conditions. There are many steps in this way, but the raw materials are relatively easy to obtain, and the reaction conditions of each step are properly controlled, resulting in better yields. For example, pyridine is first used as the starting material, halogenated under specific conditions to obtain halogenated pyridine, and then reacted with trifluoromethylating reagents under alkali catalysis, and then hydrolyzed to introduce hydroxyl groups.
Second, through the strategy of constructing pyridine rings. For example, using compounds containing trifluoromethyl groups and compounds containing functional groups such as carbonyl and amino groups as raw materials, pyridine rings are constructed through multi-step reactions, and hydroxyl groups are introduced at suitable positions at the same time. This path design is ingenious. If the reaction conditions are properly optimized, the steps can be simplified and the atomic economy can be improved. Trifluoromethyl-containing β-ketoate can be used with ammonia or amine compounds, condensed and cyclized under acidic or basic catalysis to form a pyridine ring, and then modified by subsequent reactions to introduce hydroxyl groups.
Third, the coupling reaction catalyzed by transition metals. Select suitable halogenated pyridine derivatives, with trifluoromethyl-containing borate esters or other trifluoromethylation reagents, under the action of transition metal catalysts (such as palladium, nickel, etc.), the coupling reaction occurs, trifluoromethyl is introduced, and then the hydroxylation reaction is carried out. This method has good selectivity, relatively mild reaction conditions, and does not require high equipment. The transition metal catalyst can be recycled and reused to reduce costs. For example, under the catalysis of palladium, the Suzuki-Miyaura coupling reaction of halogenated pyridine and trifluoromethylborate occurs, and the target product is obtained through the hydroxylation step.

There are currently 3-hydroxy-4- (trifluoromethyl) pyridine, and you want to know its price range on the market. This is a genus of fine chemicals, and its price is determined by multiple factors.
If the situation of raw materials, trifluoromethyl reagents and pyridine derivatives are obtained, if the raw materials are easy to purchase and the price is flat, the cost will decrease and the price will also decrease; on the contrary, the raw materials are rare and expensive, and their price will be high.
The simplicity of the production process is also the key. If the synthesis path is lengthy, multiple steps are required, and the yield of each step is not high, or special reaction conditions are required, such as high temperature, high pressure, and severe catalysts, the cost will increase and the price will also increase. However, if the process is simple and the yield is high, the price may be close to the people.
The impact of market supply and demand is also huge. If this product is in high demand in the fields of medicine, pesticides, materials, etc., and the supply is limited, the price will increase due to demand; if the market is oversupplied, the price will be reduced for competitive sales.
For the current market, the price range of this 3-hydroxy-4- (trifluoromethyl) pyridine is roughly hundreds to thousands of yuan per kilogram. However, this is only an approximate number, and the actual price should also be determined according to the specific supplier, the amount, and the time and place of transaction.
