Methyl 5-formyl-2-pyridinecarboxylate, this is an organic compound. Its physical properties are of great value for investigation, and let me explain in detail.
Under normal temperature and pressure, it is either a solid state or a liquid state, depending on its specific molecular structure and intermolecular forces. If the intermolecular forces are strong and closely arranged, it is more likely to be solid; conversely, if the intermolecular forces are weak and the movement is relatively free, it may be liquid.
When it comes to melting point, due to the presence of pyridine ring, formyl group and ester group in the molecule, the pyridine ring has a certain rigidity, and the formyl group and ester group can form intermolecular hydrogen bonds. These structural characteristics lead to enhanced intermolecular interactions, so the melting point may not be low. The specific value still needs to be determined by accurate experiments, but it can be roughly inferred that the melting point should be higher than that of hydrocarbon compounds with simple structures.
In terms of boiling point, in view of the existence of various interactions between molecules, in order to make molecules break free from each other and boil, more energy needs to be supplied, so the boiling point is also higher. And the existence of formyl group and ester group will increase the polarity of the molecule, further enhance the intermolecular force, and cause the boiling point to rise.
Solubility is also an important physical property. It is slightly soluble in water, because water is a strong polar solvent, and although the compound contains polar groups, the overall structure is not highly hydrophilic. The pyridine ring is a hydrophobic structure, and although the formyl group and the ester group are polar, it is not enough to dissolve it in water. However, in organic solvents, such as ethanol, ether, chloroform, etc., because they can form similar interactions with organic solvent molecules, such as van der Waals force, hydrogen bond, etc., the solubility is quite good.
In addition, the compound may have a certain odor, which is derived from its specific chemical structure. However, the specific odor characteristics are difficult to accurately describe by structure alone, and it is necessary to smell it yourself to perceive it. In conclusion, the physical properties of methyl 5-formyl-2-pyridinecarboxylate are controlled by its unique chemical structure, and in-depth understanding of its properties is of great significance in the fields of organic synthesis and drug development.

To prepare 2-pyridinecarboxylic acid, 5-formyl-, and methyl ester, the following ancient method can be used.
First take pyridine as the starting material, and introduce formyl based on the 5 position of the pyridine ring under specific reaction conditions. This step can be used, for example, Vilsmeier-Haack reaction, using phosphorus oxychloride and N, N-dimethylformamide as reagents.

Then, carboxylation of 5-formylpyridine is performed. With a suitable metal reagent, such as lithium reagent or magnesium reagent, and carbon dioxide, the carboxyl group can be introduced into the second position of the pyridine ring to obtain 5-formyl-2-pyridinecarboxylic acid.
In the last step, 5-formyl-2-pyridinecarboxylic acid and methanol are esterified under acid-catalyzed conditions. Commonly used acid catalysts such as sulfuric acid or p-toluenesulfonic acid are reacted under heating and reflux for a period of time to obtain the target products 2-pyridinecarboxylic acid, 5-formyl-, methyl ester. During the reaction, it is necessary to pay attention to the precise control of the reaction conditions, such as temperature, reagent dosage and reaction time, so that the reaction can be smooth and the product with higher yield can be obtained.
