This is the name of an organic compound. To know its chemical structure, it is necessary to analyze it according to the system nomenclature. " 2 - Formyl - 1,4 - dihydro - 6 - methyl - 4 - (3 - nitrophenyl) - 3,5 - pyridinedicarboxylic acid 3 - methyl 5 - (1 - methylethyl) ester "," 2 - Formyl "table 2 has formyl group;" 1,4 - dihydro "shows that the 1 and 4 positions are in the dihydrogen form;" 6 - methyl "means that the 6 position is connected with methyl;" 4 - (3 - nitrophenyl) "means that the 4 position is connected with 3 - nitrophenyl group;" 3,5 - pyridinedicarboxylic acid "epipyridine - 3,5 - dicarboxylic acid Structure. "3 - methyl 5 - (1 - methylethyl) ester" indicates that the acid is estered with methyl at the 3rd position and isopropyl at the 5th position.
According to this analysis, the compound has a pyridine ring as the core, and the 1st and 4th positions are dihydro states. Formyyl at the 2nd position, methyl at the 6th position, and 3-nitrophenyl at the 4th position. Pyridine - 3,5 - dicarboxylic acid is estered with methyl at the 3rd position and isopropyl at the 5th position, respectively. In this way, its chemical structure comes to life, just like the ancient craftsmen who joined the tenon and mortise of each component according to exquisite rules to build the structure of this organic molecule.

The physical properties of 2-formyl-1,4-dihydro-6-methyl-4- (3-nitrophenyl) -3,5-pyridinedicarboxylic acid 3-methyl-5- (1-methylethyl) ester depend on its many properties.
In terms of its appearance, it is often crystalline, which is due to its intermolecular interactions. The various groups in the molecular structure cooperate to cause the molecules to be arranged in an orderly manner and eventually crystalline. Its color or yellowish, the cause of this color, from the distribution and transition of the electron cloud in the molecule, the specific electronic structure makes the material absorb or reflect different wavelengths of visible light, so it has a yellowish color.
When it comes to the melting point, the melting point of this compound is quite high. Due to strong interaction forces between molecules, such as hydrogen bonds, van der Waals forces, etc. Among them, the pyridine ring and nitrophenyl groups and other structural units build a complex interaction network between molecules. To destroy this ordered structure and make the molecules break away from the lattice, more energy needs to be invested, so the melting point is higher.
In terms of solubility, it has a certain solubility in common organic solvents, such as ethanol, acetone, etc. This is because the compound molecule has both polar and non-polar parts. The polar carboxyl ester group can interact with polar solvents such as ethanol to form hydrogen bonds; while the non-polar benzene ring and other structures can attract each other with non-polar organic solvents through van der Waals forces, so it is soluble in various organic solvents. However, the solubility in water is not good, because the polarity of water molecules is strong, the interaction with the compound molecules is difficult to fully compensate for the energy required to break the hydrogen bond between water molecules, so it is not easily soluble in water.
The density of this compound is also affected by its molecular structure and packing method. The tight molecular packing, combined with the relatively large molecular mass, results in a moderate density. The value of its density is just one of its physical properties, reflecting the distribution of molecules in unit volume.

To prepare 2-formyl-1,4-dihydro-6-methyl-4- (3-nitrophenyl) -3,5-pyridinedicarboxylic acid 3-methyl-5- (1-methylethyl) ester, the method is as follows:
First take an appropriate amount of 3-nitrobenzaldehyde, methyl acetoacetate and 2-amino-3-methyl-4-pentenoic acid isopropyl ester, place it in a clean reactor, use anhydrous ethanol as a solvent, and add an appropriate amount of acetic acid as a catalyst. The reaction kettle is sealed, the temperature is controlled at 60-70 ° C, and the reaction is continuously stirred to fully react the reactants. This process requires careful observation of the progress of the reaction, which can be monitored by thin-layer chromatography (TLC). When the raw material point almost disappears, the reaction is almost complete.
After the reaction is completed, the reaction solution is cooled to room temperature, and then distilled under reduced pressure to remove the ethanol solvent. The remaining residue is dissolved with an appropriate amount of dichloromethane, and then washed with saturated sodium bicarbonate solution and distilled water. After the organic phase is dried with anhydrous sodium sulfate, it is distilled under reduced pressure again to remove dichloromethane and obtain a crude product.
The crude product needs to be further purified. The target fraction is collected by column chromatography with petroleum ether-ethyl acetate as eluent, concentrated under reduced pressure and crystallized to obtain pure 2-formyl-1,4-dihydro-6-methyl-4- (3-nitrophenyl) -3,5-pyridinedicarboxylic acid 3-methyl-5- (1-methethyl) ester. During the operation, all steps must follow the specifications of chemical experiments, pay attention to safety, and ensure the purity and yield of the product.
