2-benzyl-1H-pyrrolo[3,4-c]pyridine-1,3(2H)-dione

2-Benzyl-1H-pyrrolo [3,4-c] pyridine-1,3 (2H) -dione is an organic compound. Its chemical structure can be analyzed from the following aspects.
The core structure of this compound is a nitrogen-containing heterocyclic ring composed of a pyrrolido-pyridine ring system. Specifically, the pyrrole ring fuses with the pyrrolido ring in a specific way to form a pyrrolido [3,4-c] pyridine structure. Among them, 1H - indicates that there is a hydrogen atom at position 1 of the pyrrole ring; 1,3 (2H) -dione means that there are two carbonyl groups at position 1 and position 3, and the hydrogen atom at position 2 can undergo tautomerism in the keto structure.
Furthermore, 2-benzyl indicates that there is a benzyl group connected at position 2 of the pyrrolido-pyridine ring system. The benzyl group is connected to the main ring by a phenyl group through a methylene group (-CH 2O -), and the introduction of this benzyl group gives the compound unique physical and chemical properties. The conjugated structure of phenyl increases the electron delocalization of the molecule, while the methylene plays the role of connection and spacer, which affects the spatial structure and reactivity of the molecule.
In summary, the chemical structure of 2-benzyl-1H-pyrrolo [3,4-c] pyridine-1,3 (2H) -dione fuses pyrrolidine ring system, carbonyl group and benzyl group, and the interaction of each part determines the characteristics and reaction behavior of the compound.

- ** Properties **: Usually solid, but its specific appearance may vary depending on purity and crystallization conditions. Or white to light yellow crystalline powder, this color and morphology suggest its molecular arrangement and light scattering and absorption properties.
- ** Melting point **: The melting point is the temperature of the solid and liquid equilibrium of a substance, which is crucial for identification and purity judgment. Although no specific melting point data is available, it can be measured that its melting point is helpful for purity evaluation. The melting point of pure products is sharp, and the melting point decreases and the melting range becomes wider when mixed with impurities.
- ** Solubility **: The compound has certain hydrophobicity and has limited solubility in polar solvents such as water, but it is soluble in common organic solvents, such as dichloromethane, chloroform, N, N-dimethylformamide (DMF), etc. Good solubility in dichloromethane is due to the matching of its molecular structure with intermolecular forces such as van der Waals forces between dichloromethane and dipole-dipole interactions. This dissolution property is of great significance for its synthesis, separation and application. Organic solvents are commonly used as reaction media in organic synthesis. < Br > - ** Stability **: It is relatively stable in normal temperature, pressure and dry environment, but if exposed to strong acid, strong base or high temperature environment, or chemical reaction causes structural changes. Under the action of strong base, its molecular lactam bond or hydrolysis changes its chemical structure and properties. Therefore, it is necessary to control environmental conditions during storage and use to avoid contact with active substances. < Br > - ** Spectral Properties **:
- ** Infrared Spectroscopy **: The carbonyl group (C = O) in the molecule is at 1600-1800 cm fond or at the current strong absorption peak, characterizing the characteristic functional group vibration; the carbon-carbon double bond vibration absorption peak of the benzene ring may be seen in the range of 1450-1600 cm fond, and the pyrrolido-pyridine ring will also show absorption peaks in a specific wavenumber range, which helps to confirm the structure.

Each hydrogen atom has different chemical shifts due to its different chemical environments. If the chemical shifts of hydrogen atom on benzyl group and hydrogen atom on pyrrolidine ring are different, the ratio of integral area corresponds to the ratio of the number of hydrogen atoms, which is helpful for structure analysis.
