What are the physical properties of 3,3 '- [ (4- {[ (E) -2-bromo-4-nitro-6- (trifluoromethyl) phenyl] diazenyl} phenyl) imino] dipropanenitrile

This is 3,3 '- [ (4- {[ (E) -2-bromo-4-nitro-6- (trifluoromethyl) phenyl] diazo} phenyl) imino] dipropionitrile. Its physical properties are as follows:

This substance is often in a solid state, because the molecule contains a variety of polar groups such as diazo group and cyano group, and the intermolecular force is strong, so it mostly exists in solid form at room temperature and pressure. Its melting point and boiling point are affected by the interaction of various groups in the molecular structure. The existence of diazo groups makes the molecule relatively unstable. Under heat or specific conditions, diazo groups are prone to decomposition and other reactions, resulting in its melting point and boiling point difficult to accurately determine. But in general, in view of the high polarity of the cyanyl group and the enhancement of the intermolecular force of the diazo group, it is speculated that its melting point and boiling point are relatively high.

In terms of solubility, because the molecule contains hydrophobic groups such as bromine, nitro, and trifluoromethyl, and although the cyanyl group is polar, it is not enough to resist the influence of many hydrophobic groups, so the solubility in water is extremely low. In halogenated hydrocarbon organic solvents such as dichloromethane and chloroform, as well as polar organic solvents such as acetonitrile, it should have a certain solubility by virtue of the similar miscibility principle. The specific solubility value varies depending on the type of solvent, temperature and other conditions. < Br >
In appearance, it may be white to light yellow solid powder, and the color origin is related to chromophores such as diazo groups and nitro groups. The structure of diazo groups and nitro groups can absorb visible light of specific wavelengths, resulting in a certain color of the substance. And different batches of products may have different appearance colors and powder fineness due to differences in purity and crystalline state.

Density is closely related to the atoms and groups of the molecule. Bromine atoms have a large relative atomic weight, trifluoromethyl contains fluorine atoms, and the atoms in the molecule are closely connected, resulting in a higher overall density, which is greater than that of common organic solvents such as ethanol and ether. In organic synthesis experiments, the phase distribution and other properties of its participation in the reaction are related to the density.
