The synthesis of 4- (trifluoromethyl) -2 -pyridinecarboxylic acid covers a variety of pathways. First, the corresponding pyridine derivative can be started. First, find a pyridine containing a suitable substituent, such as 4-halogenated pyridine, the halogen atom can be chlorine, bromine and the like. Then, with a trifluoromethyl reagent, such as trifluoromethyl magnesium halide and other Grignard reagents, the nucleophilic substitution reaction occurs with it, and the halogen atom is then replaced by trifluoromethyl to obtain 4- (trifluoromethyl) pyridine. Then, a carboxyl group is introduced at the 2-position of pyridine. The localization effect of the nitrogen atom of the pyridine can be used to form a pyridine ring through a metallization reaction, such as interacting with a strong base such as butyl lithium, so that the 2-position hydrogen is replaced by lithium, and then reacts with carbon dioxide. After acidification, 4- (trifluoromethyl) -2 -pyridine carboxylic acid can be obtained.
Second, the construction of a pyridine ring can also be started. Compounds containing trifluoromethyl and carboxyl precursors are used to construct a pyridine ring through multi-step reactions. For example, under suitable catalyst and reaction conditions, a series of reactions such as condensation and cyclization are used to form a pyridine ring, and trifluoromethyl and carboxyl groups are introduced at suitable positions. After appropriate modification, the target product can also be obtained.
Furthermore, the structure modification of existing similar compounds can also be achieved. If a pyridine carboxylic acid derivative with a similar structure is found, and it contains a group that can be converted into trifluoromethyl, such as a group that can be halogenated and reacted with a trifluoromethylation reagent, the group can be converted into trifluoromethyl through a specific reaction, and 4- (trifluoromethyl) -2 -pyridinecarboxylic acid can also be obtained. Each method has its own advantages and disadvantages, and it needs to be carefully selected according to factors such as the availability of actual raw materials, the ease of control of reaction conditions, and cost.

I think what you are asking is about 2-pyridinecarboxylic acid, 4- (trifluoromethyl) in the market price range. However, the price of this chemical often changes due to various factors, and it is difficult to directly determine its exact price.
First, the situation of supply and demand really determines the price. If the market is crowded and the supply is limited, the price will increase; conversely, if the supply exceeds the demand, the price may drop. Second, the cost of raw materials also has a great impact. The preparation of this chemical requires specific raw materials, and the rise and fall of the price of raw materials will cause the price of finished products to change. Third, the preparation process and technology are also related to the cost and price. Advanced technology may reduce costs, but the research and development and application of new technologies may increase upfront investment.
In addition, different merchants and regions have different prices. Generally speaking, in the chemical raw material market, the price of such chemicals may vary depending on the purity, packaging, and purchase quantity. If the purchase quantity is small and the purity is high, the price per gram or a few yuan to a few tens of yuan; if it is a large purchase, such as kilogram or more, the price per kilogram may be between a few hundred yuan and a few thousand yuan. However, this is only a rough guess. The actual price needs to be consulted in detail with the chemical raw material supplier, or checked in detail on the chemical product trading platform, in order to obtain a more accurate price.
