The synthesis of 6-chloro-2- (difluoromethyl) pyridine-3-carboxylic acids is one of the key issues in organic synthetic chemistry. The common method for synthesizing this compound can be started by a compound containing a pyridine structure.
One method is to take a suitable pyridine derivative first, which requires a substituted group at a specific position in the pyridine ring. If 2-methyl-3-pyridinecarboxylic acid is used as the starting material, the 2-position methyl group is first halogenated, and suitable halogenating reagents, such as chlorine gas or chlorine-containing reagents, can be selected. Under appropriate reaction conditions, such as suitable temperatures and catalysts, the methyl group is converted to chloromethyl group, and then 6-position chlorination is achieved. Subsequently, the difluoromethylation reaction of chloromethyl is carried out, and the reagent containing difluoromethyl can be selected, such as the difluoromethylation reagent TMSCF ³ Br, etc. Under the action of alkali, the reaction occurs to convert chloromethyl to difluoromethyl, so that the target product 6-chloro-2- (difluoromethyl) pyridine-3-carboxylic acid can be obtained.
Another method can start from the construction of pyridine ring. Pyridine ring is constructed by multi-step reaction using small molecule compounds containing nitrogen and carbon. For example, a suitable nitrile compound and a fluorine-containing enol ether compound are cyclized to construct a pyridine ring under specific catalysts and reaction conditions. During the cyclization process, the reaction conditions and raw material structures are cleverly designed to introduce chlorine atoms and difluoromethyl groups into the pyridine ring at the appropriate position, and at the same time, a carboxyl group is constructed at the 3-position. This process requires precise control of the reaction conditions of each step, such as temperature, reaction time, and reagent dosage, to ensure that the reaction proceeds in the direction of generating the target product. And after each step of the reaction, suitable separation and purification methods, such as column chromatography and recrystallization, are required to improve the purity of the product and lay a good foundation for subsequent reactions.

6-Chloro-2- (difluoromethyl) pyridine-3-carboxylic acid, which is an important organic synthesis intermediate in the field of fine chemicals, is widely used in many fields such as pesticides and medicine. However, its market price fluctuates and is influenced by many factors.
Let's talk about the supply end of raw materials first. If the supply of chlorine and difluoromethyl related raw materials required for the preparation of this compound is abundant and stable, the price will stabilize; if the supply of raw materials is in short supply, in case of natural disasters, geopolitical production is blocked, or environmental protection policies tighten some raw material manufacturers to reduce production and stop production, the price of raw materials will rise, which will then promote the price of 6-chloro-2- (difluoromethyl) pyridine-3-carboxylic acid to rise.
On the market demand side, in the field of pesticides, if the new high-efficiency pesticides containing this ingredient are successfully developed and the marketing activities are good, the demand for them will increase greatly, and the price may rise due to shortage; in the pharmaceutical industry, if the new drugs with this intermediate are approved for listing, the demand will also surge, driving up prices. On the contrary, if the demand in the downstream industry is sluggish, the price will be difficult to have upward momentum.
There are also production processes and production capacity factors. Advanced production processes can improve production efficiency and reduce costs. If most companies master advanced processes, the market supply will increase and the price may drop. If the production process is complex and the production capacity is limited, the supply will be difficult to meet the demand, and the price will be high.
In the current market, the price fluctuates roughly between tens of yuan and hundreds of yuan per kilogram. For small batch purchases, the price may be in a higher range, hundreds of yuan per kilogram; for large batch purchases and long-term cooperation, due to scale effects, suppliers may give discounts, and the price may be reduced to tens of yuan per kilogram. However, when the specific price needs to be purchased, consult each supplier in detail and consider the actual market conditions.
