Sodium-5-chloro-4-ethyl-2-[ (2-hydroxy-1-naphthyl) azo] benzenesulfonate, an organic compound. Its physical properties are important for its application in many fields.
Looking at its appearance, it is usually in a powdery or crystalline state, and its color may be light yellow to orange. This color is derived from the azo group in the molecular structure, which has a conjugated system and can absorb visible light at specific wavelengths, causing the compound to develop color.
In terms of solubility, due to the sulfonate group, it has a certain hydrophilicity and can be partially dissolved in water to form a stable solution. However, its solubility is also affected by factors such as temperature and pH value of the solvent. When the temperature increases, the solubility may increase; under specific pH conditions, the degree of ionization changes and the solubility also changes.
Melting point and boiling point are key physical properties. The exact melting point and boiling point data need to be determined experimentally, but can be inferred according to the structure. The compound has van der Waals forces, hydrogen bonds and other interactions between molecules, resulting in a relatively high melting point. To make it melt or boil, enough energy is required to overcome the intermolecular forces.
In addition, density is also one of the physical properties. Although the exact value needs to be determined experimentally, the structure and similar compounds can be roughly inferred. Because the molecule contains structural units such as benzene ring and naphthalene ring, the relative molecular weight is large, and the atoms are closely arranged, so the density may be relatively large.
The physical properties of this compound are important for its production, storage, transportation and application. Understanding these properties can better control its behavior and use.
