Looking at its morphology, or in a crystalline state, because many compounds containing such structures exist in this form under normal conditions, with regular lattice arrangement. When the appearance is often solid and the texture is relatively pure, it is crystal clear.

When it comes to melting point, the atoms in the molecule are closely connected by covalent bonds to form a specific spatial structure, and the interaction between atoms is strong. Therefore, the melting point may be higher, and more energy is required to break the lattice structure to make it melt, or above 100 degrees Celsius. The specific value depends on the details of the intermolecular interaction.

In terms of solubility, molecules containing polar groups, such as methoxy, oxy, etc., may have a certain solubility in polar solvents. For example, in organic solvents such as ethanol and acetone, due to the principle of "similar miscibility", polar groups interact with polar solvent molecules to help them dissolve. However, in non-polar solvents, such as n-hexane, the solubility may be very low. < Br >
In terms of stability, the heterocyclic and benzene rings in the molecular structure endow it with certain stability, and the conjugated system can disperse electrons and reduce molecular energy.
