4,4 '-Dicarbox-2,2' -biquinoline is an organic compound. Its physicochemical properties are particularly important for its application in many fields.
The properties of this compound are either solid under normal conditions and have a specific crystalline form. Its melting point is quite high, reflecting strong intermolecular forces and relatively stable structure. Melting requires more energy to overcome the attractive forces between molecules, and the melting point is in a certain high temperature range.
In terms of solubility, it may exhibit specific solubility in common organic solvents. In polar organic solvents, such as ethanol, acetone, etc., it may have a certain solubility, because polar groups such as carboxyl groups in the molecule can form hydrogen bonds or other interactions with polar solvent molecules. However, in non-polar solvents, such as n-hexane, benzene, etc., the solubility may be very low, due to the weak force between the polar structure and the non-polar solvent.
