The sodium salt of 3-hydroxy-4- (1-hydroxy-2-naphthyl azo) -1-naphthalenesulfonic acid, whose chemical structure consists of naphthalene ring, hydroxy group, sulfonic acid group and azo group.
There are two naphthalene ring structures in this compound, one of which is connected to the hydroxyl group at 1 position, and the second position is connected to the fourth position of the other naphthalene ring through the azo group (-N = N-). There is a hydroxyl group at the 3rd position of the naphthalenesulfonic acid connected to the azo group, and the hydrogen on the sulfonic acid group is replaced by sodium to form a sodium salt. The naphthalene ring, as a fused aromatic hydrocarbon structure, provides the basic skeleton and conjugate system for the whole molecule, which affects its physical and chemical properties such as stability, electron cloud distribution, etc. Hydroxy group (-OH) has certain hydrophilicity and reactivity, and can participate in hydrogen bond formation and some chemical reactions, such as esterification, oxidation, etc. Azo group (-N = N-), as a chromophore, often gives the compound a color, which is widely used in dyes and other fields. Its double bond structure also has certain chemical activity. The sulfonic acid group (-SO 🥰 H) enhances the solubility of the compound in water after forming a sodium salt. The structure of -SO 🥰 Na 🥰 helps the substance to disperse and dissolve in polar solvents, which is beneficial to its role in aqueous systems in industrial production and practical applications.
What are the physical properties of 3-Hydroxy-4- (1-Hydroxy-2-Naphthylazo) -1-Naphthalenesulfonic Acid, Sodium Salt?

In terms of solubility, it is soluble in water, which makes it well dispersed in aqueous solution systems, making it easy to participate in reactions or function in various aqueous environments.
From the melting point point point of view, due to the existence of many interactions in the molecular structure, such as hydrogen bonds, dipole-dipole interactions, etc., its melting point is relatively high. These intermolecular forces stabilize the lattice structure and require high energy to destroy it, thus making it thermally stable.
Its density is similar to that of general organic sodium salts. Due to the fact that the molecule contains multiple aromatic rings and sulfonic acid groups, the relative molecular weight is relatively large, making it higher in unit volume.
This sodium salt is quite stable at room temperature and pressure. The naphthalene ring and azo group in the molecular structure give it a certain conjugate system, which enhances the stability. However, if the ambient temperature is too high, the light is too strong, or it is in extreme conditions such as strong acid and alkali, its structure may be damaged, causing color changes or chemical properties to change. Furthermore, it has a certain surface activity, because the sulfonic acid group is hydrophilic, while the naphthalene ring is partially hydrophobic. This amphiphilic structure allows it to change the surface properties at the interface and can be used for specific surface treatments or as an additive to certain systems.
