3-Bromo-1H-pyrrolo[2,3-b]pyridine

3 - Bromo - 1H - pyrrolo [2,3 - b] pyridine is an organic compound with unique physical properties. It is mostly solid at room temperature, and its appearance may be white to pale yellow crystalline powder. This morphology is due to the interaction and arrangement of molecules, resulting in the orderly accumulation of molecules into a solid lattice structure.
The melting point of this compound is of great significance for its purification and identification. Experiments have determined that the melting point is about [specific value] ℃. At this temperature, the lattice can reach equilibrium with the thermal motion of the molecule, the lattice disintegrates, and the substance changes from solid to liquid state. The exact value of the melting point is affected by the purity of the compound, and impurities will interfere with the lattice structure, reducing the melting point and widening the melting range. The solubility of 3-Bromo-1H-pyrrolo [2,3-b] pyridine in organic solvents is also of concern. It exhibits good solubility in common organic solvents such as dichloromethane, chloroform, and N, N-dimethylformamide (DMF), because these solvents can form interactions such as van der Waals force and hydrogen bonds with compounds, which help the molecules to disperse uniformly. However, the solubility in water is poor, because the molecular polarity does not match that of water, and it is difficult for water molecules to overcome the intermolecular interactions of compounds to disperse them.
The density of this compound is also an important physical property. Its density is about [specific value] g/cm ³, which reflects the mass of the substance per unit volume and is closely related to the molecular structure, atomic species and arrangement.
In addition, 3-Bromo-1H-pyrrolo [2,3-b] pyridine has certain stability, but it may participate in chemical reactions under specific conditions. Because of its bromine-containing atom and pyrrolido-pyridine structure, the bromine atom activity enables the compound to undergo nucleophilic substitution reactions, and the pyrrolido-pyridine structure conjugate system endows it with certain electronic properties, which can participate in electron transfer-related reactions. Understanding these physical properties is of great significance for its application in organic synthesis, drug development and other fields.
