This is the synthesis method of Ruyan 2-pyridinecarboxylic acid, 5-chloro-3-methyl.
To prepare this substance, the corresponding pyridine derivative is often the beginning. First select the appropriate substituted pyridine, and the substituent distribution on it needs to be planned for the reaction. For example, select the group that can be converted into the target substituent.
One method uses the pyridine derivative containing a suitable halogen atom as the starting material. The halogen atom has high activity and can be introduced into the desired group by nucleophilic substitution reaction. If chloropyridine is selected, use a suitable methylation reagent, and under suitable base and reaction conditions, carry out a methylation reaction to introduce methyl. The choice of base is very critical. Common potassium carbonate, sodium carbonate, etc., depend on the characteristics of the reaction system. The reaction temperature and time also need to be precisely controlled. Generally, heating and stirring in an appropriate organic solvent is required to make the reaction fully proceed.
After methylation is completed, the chlorination step is carried out. Chlorination can be done with suitable chlorination reagents, such as chlorine gas, thionyl chloride, etc. Under suitable reaction conditions, chlorination of the pyridine ring at a specific position is obtained to obtain a 5-chlorine substitute. This step requires attention to the reaction selectivity, which can be achieved by means of catalysts or controlled reaction conditions.
Or from another perspective, chlorination first and then methylation are also feasible paths. However, the reaction conditions of each step need to be optimized in detail according to the characteristics of the reactants, reaction equipment and other factors to ensure the yield and product purity of each step.
In the synthesis process, separation and purification techniques are often required after each step of the reaction, such as extraction, distillation, column chromatography, etc., to remove impurities and obtain pure intermediates or final products 2-pyridinecarboxylic acid, 5-chloro-3-methyl. And each step of the reaction requires analysis and detection methods, such as nuclear magnetic resonance, mass spectrometry, etc., to confirm the structure and purity of the product to ensure the correctness and effectiveness of the synthesis route.

Today, I have a question. What is the price range of 2-pyridinecarboxylic acid, 5-chloro-3-methyl in the market. This is a product in the field of fine chemicals, and its price often varies due to multiple factors.
First, the price of raw materials has a great impact. If the starting materials required to synthesize this compound are scarce or the price fluctuates violently, the cost will rise and fall, which in turn affects the price. Second, the simplicity of the preparation process is also critical. If complex reaction steps, harsh reaction conditions, or special catalysts are required, the cost will increase significantly and the price will be high. Furthermore, the state of market supply and demand determines the price. If demand is strong and supply is limited, the price will rise; conversely, if supply exceeds demand, the price will fall.
Then check the records of past transactions and the analysis of market conditions. The price per gram of 2-pyridinecarboxylic acid and 5-chloro-3-methyl may range from tens to hundreds of yuan. For small-scale scientific research procurement, due to small quantities and high requirements for purity, the unit price may be at the top of the price range. If it is an industrial-scale procurement, you can get discounts due to large quantities, and the unit price may be near the bottom. However, the market is changing, and the actual price should be subject to the current quotations of various suppliers. Buyers should inquire more and compare prices to get a suitable price.
