Looking at its appearance, it is often a white to light yellow crystalline powder, delicate and uniform, slightly shiny in the sun, like finely crushed jade chips. Its melting point is quite high, about 240-245 ° C. This high melting point indicates strong intermolecular forces and relatively stable structure. When heated to the melting point, it gradually changes from a solid state to a liquid state, similar to the melting of ice and snow, but the process requires a stable and sufficient heat supply.
As for solubility, 4,4' -dipyridyl benzyl behaves differently in common organic solvents. In alcoholic solvents such as methanol and ethanol, there is a certain solubility. Although it is not very soluble, it can be partially dissolved by proper heating and stirring to form a slightly cloudy or clear solution.
