8- {[5- (4-methylphenyl) thiopheno [2,3-d] pyrimidine-4-yl] oxy} quinoline is an organic compound, its physical properties are very critical, and it is of great significance in chemical research and application fields.
Looking at its appearance, this compound is often in solid form due to strong intermolecular forces and orderly arrangement of molecules. Its color is mostly white or off-white, which is due to the absorption and reflection characteristics of the molecular structure to visible light. The chemical bonds and electronic transitions in the molecule determine the absorption of specific wavelengths of light, so that the rest of the visible light is reflected white or off-white. < Br >
When it comes to melting point, the compound has a certain melting point range, which is closely related to the intermolecular forces. Intermolecular forces such as van der Waals forces and hydrogen bonds require specific energy to overcome, causing the lattice structure to disintegrate and realizing the transition from solid to liquid. The exact melting point value is of great significance for the determination of the purity of the compound. The melting point range of high-purity compounds is narrow. If it contains impurities, the melting point decreases and the range becomes wider.
In terms of solubility, the dissolution of this compound in organic solvents varies. In general, it has good solubility in polar organic solvents such as dimethyl sulfoxide (DMSO) and N, N-dimethylformamide (DMF), because these solvents can form strong interactions with compound molecules, such as hydrogen bonds and dipole-dipole interactions, which help molecules disperse in solvents. However, in non-polar organic solvents such as n-hexane and toluene, the solubility is poor, because the interaction between non-polar solvents and polar compounds is weak. The solubility in water is also poor, because the molecular polarity is not enough to form an effective interaction with water molecules, and the hydrophobic group affects its dispersion in water.
In addition, the physical properties such as the density and boiling point of the compound are also determined by the molecular structure and intermolecular forces. The density reflects the mass of the substance per unit volume and is related to the molecular weight and the way of molecular accumulation; the boiling point is related to the magnitude of the intermolecular force. The stronger the force, the higher the boiling point.
