The physical properties of 1H-pyrazolo [4,3-c] pyrazole, 6-bromine are as follows:
This compound often appears as a crystalline solid in appearance, and forms a regular lattice structure due to the orderly arrangement of atoms in the molecular structure. It exists stably at room temperature and pressure. Its stability is derived from the conjugated structure of pyrazolo-pyrazole rings, which makes the electron cloud distributed uniformly and enhances molecular stability.
In terms of melting point, it is usually in a certain temperature range, and the specific value varies due to purity and other factors. Interactions such as van der Waals forces and hydrogen bonds exist between molecules. It is necessary to absorb enough energy to overcome these effects before the lattice can disintegrate and the substance can melt.
Solubility, slightly soluble in water. Due to the hydrophobicity of the molecule as a whole, the pyrazole-pyrazole ring and the non-polar part of the bromine atom account for a large proportion, and the ability to form hydrogen bonds with water molecules is weak. As a polar solvent, water has limited solubility. However, it is soluble in some organic solvents, such as dichloromethane, chloroform, N, N-dimethylformamide (DMF), etc. In non-polar or weakly polar organic solvents such as dichloromethane, the van der Waals force between the molecule and the solvent is conducive to its dispersion and dissolution; in polar organic solvents such as DMF, although the overall hydrophobicity, the polar part can form a weak interaction with DMF to promote its dissolution. < Br >
The density is related to the relative molecular weight and the degree of molecular packing. Due to the structure of the pyrazole-pyrazole ring system and the existence of bromine atoms, the relative density is higher. The atomic weight of bromine atoms is larger, which increases the molecular weight, and the molecular structure is relatively tightly packed, which increases the mass per unit volume.
