4,5-Dihydro-4-oxofuro[3,2-c]pyridine

The 4,5-dihydro-4-oxofurano [3,2-c] pyridine is an organic compound. Its physical properties are quite explainable.
First of all, its appearance is usually a crystalline solid, with a color close to white, delicate and regular, and it is like a fine jade chip with a warm luster. This morphology is closely related to the arrangement and interaction of atoms in its molecular structure, and the intermolecular force prompts it to be arranged in an orderly manner, eventually forming a crystalline shape.
The melting point has been measured by many experiments, and the phase transition occurs within a certain temperature range. The value of this melting point is similar to the characteristic identification of the compound, which is determined by the strength of the intermolecular force and the tightness of the structure. Strong intermolecular forces require higher energy to break them, causing the melting point to rise; otherwise, it is low.
And solubility, in common organic solvents, its performance varies. In polar organic solvents such as ethanol, it is slightly soluble. Because ethanol has polar groups, it can interact with the partial structure of the compound such as hydrogen bonds, so it is compatible. However, in non-polar solvents such as n-hexane, the solubility is not good, because the types of intermolecular forces between the two are different, and it is difficult to dissolve.
Its density is also an important physical property. Compared with water, it is slightly different, which reflects the relationship between the molecular mass and the occupied space, and the density value can provide a basis for identification and related applications.
As for volatility, it is very weak. Due to the relatively strong intermolecular force, it takes a lot of energy for molecules to escape from the liquid surface and enter the gas phase, so they rarely evaporate into the air at room temperature and pressure.
These physical properties are the basis for the study of this compound, and have important guiding significance in many fields such as chemical synthesis and drug development.
