4-Methylpyridine-3-carboxylic acid is 4-methylpyridine-3-carboxylic acid, which has the following physical properties.
Its appearance is often white to light yellow crystalline powder. The melting point is in a specific range, about 185-189 ° C. In this temperature range, the substance changes from solid to liquid. The substance exhibits a certain solubility in water. Because the nitrogen atom and carboxylic group of the pyridine ring in the molecule can form hydrogen bonds with water molecules, it has a certain degree of solubility in water, but the solubility is limited. In organic solvents, such as ethanol and acetone, its solubility is relatively good. This is due to the principle of similarity and miscibility. The structure of 4-methylpyridine-3-carboxylic acid has a certain similarity with these organic solvents, and the intermolecular force is conducive to its dispersion.
4-methylpyridine-3-carboxylic acid has a certain smell, but the smell is not strong and pungent, and it is a relatively slight and special organic compound smell. Its density is also an important physical property. Although the exact value will vary slightly depending on the measurement conditions, it is roughly within a specific range, which affects its distribution when mixed with other substances. In addition, it exists stably at room temperature and pressure, and its state does not change spontaneously. However, it encounters special conditions such as high temperature and open flame, or a chemical reaction occurs, which alters its original physical form and chemical properties.

The synthesis method of 4-methylpyridine-3-carboxylic acid, through the ages, chemists have explored several ways. One is to use 4-methylpyridine as the starting material and add carboxyl groups through oxidation reaction. Commonly used oxidants include strong oxidants such as potassium permanganate and potassium dichromate. Although this method is classic, the reaction conditions are relatively strict, and it needs to be carried out under heating and strongly alkaline environment. The requirements for reaction equipment are quite high, and there are many side reactions, and the product separation and purification are also difficult.
The second is to start from compounds containing pyridine rings and construct target molecules through a series of complex substitution reactions. For example, suitable halogenated pyridine derivatives can be selected to undergo nucleophilic substitution reaction with reagents containing carboxyl precursors under the action of specific catalysts and bases. The key to this path lies in the selection of halogenated pyridine derivatives and the precise control of reaction conditions to ensure that the reaction proceeds in the desired direction while minimizing the occurrence of side reactions. The advantage of this method is that the reaction check point can be accurately regulated, and the product selectivity is relatively high. However, the synthesis steps are complicated and the operation technology is very strict.
Third, some studies use transition metal-catalyzed cross-coupling reactions to synthesize 4-methylpyridine-3-carboxylic acids. Using a halide or borate containing a pyridine skeleton as a substrate and a suitable carboxylation reagent, under the catalysis of transition metal catalysts (such as palladium, copper, etc.), the formation of carbon-carbon bonds or carbon-hetero bonds is achieved, and then the target product is obtained. Such methods have relatively mild reaction conditions and high atomic economy, which have attracted much attention in recent years. However, the cost of transition metal catalysts is high, and the recovery and repurpose of some catalysts need to be further studied, which limits their large-scale industrial application to a certain extent.
