The synthesis method of 4-bromo-6-chloro-2-methoxybenzoic acid can be obtained from the following ways.
First, the corresponding phenols are used as starting materials. First, the phenol and the halogenated hydrocarbon are reacted in an alkaline environment to achieve methoxylation. For example, phenol and bromomethane react with potassium carbonate and other bases in a suitable organic solvent, such as N, N-dimethylformamide (DMF), in a certain temperature to obtain methoxylation products. Subsequently, by halogenation reaction, bromine and chlorine atoms are introduced at specific positions in the aromatic ring. For example, in the presence of a suitable catalyst, such as iron powder or iron trihalide, it reacts with bromine, chlorine elemental substance or its corresponding halogenation reagent in an appropriate solvent, regulates the reaction conditions, and achieves precise halogenation at the desired position. Finally, through carboxylation reaction, a specific group is converted into a carboxyl group. For example, carbon dioxide is used as the carboxyl source, and under the action of a metal catalyst, carboxylation is realized to obtain the target product 4-bromo-6-chloro-2-methoxybenzoic acid.
Second, halogenated aromatics are used as the starting material. Methoxy groups are introduced first, and nucleophilic substitution reactions can be used to react with halogenated aromatics with methoxylation reagents such as sodium methoxide, and react with methoxylation reagents such as sodium methoxide After that, the carboxylation reaction can be carried out, and the Grignard reagent method can be borrowed. Halogenated aromatics are first made into Grignard reagents, such as reacting with magnesium chips in anhydrous ether or tetrahydrofuran to make Grignard reagents, and then reacting with carbon dioxide, followed by acidification treatment to obtain carboxyl-containing products. Finally, under suitable conditions, another halogen atom is introduced at a specific position on the aromatic ring, and through a series of reactions, 4-bromo-6-chloro-2-methoxybenzoic acid is synthesized.
Third, benzoic acid derivatives can be considered as starting materials. First, bromine and chlorine atoms are introduced in sequence on the aromatic ring of benzoic acid, and halogenation reactions are used to control the conditions to replace the halogen atoms at the designated positions. After that, the target product 4-bromo-6-chloro-2-methoxybenzoic acid is synthesized by methoxylation reaction, methoxy group is added, such as nucleophilic substitution mechanism, and suitable methoxylation reagent. All methods need to consider the reaction conditions, reagent selection and product separation and purification to achieve a good synthesis effect.

The price of 4-6-alkane-2-carboxylic acid in the market is determined by the price. The price of this compound is often affected by general factors.
First, the cost of raw materials. If the raw materials are rare and available, or the cost of collection and extraction is high, the price of carboxylic acid will rise. Second, the synthesis is easy. If the synthesis method is complicated, multiple processes are required, and the rate of reaction of each step is not high, or special equipment is required, which will increase the cost and make the market go up. Third, the supply and demand of the market. If the market has a strong demand for this carboxylic acid, but the supply is limited, the price of natural water will be high; conversely, if the supply is limited, the price will drop.
However, roughly speaking, if this is the case and the synthesis is easy, the price per gram may be between ten and one or two hundred words. If the synthesis is hard, or the raw materials are rare, the price per gram or more than 100 words, even as high as a thousand gold is unknown. In addition, if you want to obtain the price of the refined price, you can test the general factors, according to the market conditions below.
