2-Methyl-3-hydroxy-quinoline-4-carboxylic acid, this is an organic compound. Its physical properties are quite important and are related to applications in many fields.
Looking at its properties, under normal conditions, it may be a solid. Due to the strong intermolecular forces, the molecules are arranged in an orderly manner, resulting in a certain shape and volume. As for the color, or in the form of a white to light yellow powder, the formation of this color is related to the distribution of electron clouds and energy level transitions in the molecular structure. Specific chemical bonds and groups in the molecule absorb visible light of a specific wavelength and reflect other wavelengths, thus showing the corresponding color.
Its melting point is also a key physical property. The value of the melting point depends on the magnitude of the intermolecular force. There may be hydrogen bonds and van der Waals forces between the molecules of this compound. The existence of hydrogen bonds greatly enhances the attraction between molecules, so that higher temperatures are required to break this force and increase the melting point. After experimental determination, its melting point may be within a specific range, which can provide an important reference for related synthesis and purification processes.
In terms of solubility, the solubility in water is poor. Although the molecular structure contains hydrophilic groups such as hydroxyl and carboxyl groups, the presence of quinoline rings makes the molecule as a whole more hydrophobic. The quinoline ring is an aromatic ring structure with a uniform distribution of electron clouds, which makes it difficult to form effective interactions with water molecules. However, in organic solvents, such as ethanol, dichloromethane, etc., there may be some solubility. The hydroxyl group of the ethanol molecule can form hydrogen bonds with the hydroxyl group and carboxyl group of the compound, enhancing the interaction and promoting the dissolution.
In addition, the density of the compound also has its own characteristics. The density is related to the molecular mass and the degree of molecular packing compactness. Its molecular structure is relatively complex, the number of atoms is large, and the molecular mass is large. And the molecular arrangement or relatively close, so that the density may be in a certain value range, which is of guiding significance for the separation and mixing of substances in a specific system.
