What are the physical properties of [1,1 '-biphenyl] -2,2' -disulfonic acid, 4,4 '-bis [ (2-hydroxy-6-sulfonic acid-1-naphthyl) azo] -, tetrasodium salt (9CI)?

9CI number tetraazolone, its full name is 1,1 '-binaphthalene-2,2' -disulfonic acid, 4,4 '-bis [ (2-methylamino-6-sulfonic acid-1-naphthalene) azo] -, tetrasodium salt (9CI). This substance has the following physical properties:
In terms of appearance, it is mostly in the form of solid powder, and the color is often bright. This is mainly due to the azo structure contained in it. The azo group can usually give the compound a more vivid color. In many dyes and pigments, the azo structure is widely present, which also makes the tetraazolone have similar color characteristics.
In terms of solubility, due to the presence of a sulfonic acid group in the molecule, the sulfonic acid group is a strong hydrophilic group, so the substance has a certain solubility in water and can be combined with water molecules through ion-dipole interactions to form a uniform solution system. However, the solubility in organic solvents is relatively complex. Generally speaking, for polar organic solvents, such as methanol, ethanol, etc., there may be a certain solubility. This is because some of its structures have similar polar characteristics to polar organic solvents and follow the principle of similar compatibility. For non-polar organic solvents, such as benzene, toluene, etc., the solubility is poor because the overall polarity of the molecule is different from that of non-polar organic solvents.
In terms of stability, the azo structure in this substance may decompose or rearrange under conditions such as light and high temperature. The photon energy in light may break the azo bond, causing the change of molecular structure; the high temperature environment will also increase the internal energy of the molecule, promoting the change of the azo structure, which in turn affects the stability of the whole substance. In addition, its sodium salt form is relatively stable, because the ionic bond formed by sodium ions and sulfonate ions enhances the stability of the molecular structure to a certain extent, so that the substance can maintain a relatively stable state under general storage conditions.

What is the preparation method of [1,1 '-biphenyl] -2,2' -disulfonic acid, 4,4 '-bis [ (2-hydroxy-6-sulfonic acid-1-naphthyl) azo] -, tetrasodium salt (9CI)?

Method for preparing tetralin (9CI)
To obtain [1,1 '-binaphthalene] -2,2' -disulfonic acid, 4,4 '-bis [ (2-methylamino-6-sulfonic acid-1-naphthalene) azo] -tetralin (9CI), you can follow the following ancient method.
First take an appropriate amount of [1,1' -binaphthalene] and place it in a special kettle. Following the delicate method, the sulfonic acid group is introduced, and the 2,2 '-position is precisely added to it to obtain [1,1' -binaphthalene] -2,2 '-disulfonic acid. This process needs to be controlled at a suitable temperature and observed for subtle changes to obtain the best product.
Wait until [1,1 '-binaphthyl] -2,2' -disulfonic acid is ready, and take the raw material of 2-methylamino-6-sulfonic acid-1-naphthyl. With the ancient technique of azo synthesis, the 4,4 '-position is coupled to it in a rigorous atmosphere. This step requires various reagents, which are properly reconciled and the temperature is suitable, so that the azo reaction can proceed smoothly, so that the bis [ (2-methylamino-6-sulfonic acid-1-naphthyl) azo] structure is stable at the 4,4' -position.
During the whole preparation process, the purity and dosage of raw materials, the temperature and time of reaction need to be carefully controlled. The utensils used also need to be clean and unstained to ensure the quality and purity of the product. And when operating, you need to follow the ancient rules, work with respect, and do not slack in the slightest. In this way, you can get the four hooks (9CI).

What are the environmental effects of [1,1 '-biphenyl] -2,2' -disulfonic acid, 4,4 '-bis [ (2-hydroxy-6-sulfonic acid-1-naphthyl) azo] -, tetrasodium salt (9CI)?

I look at this "[1,1 '-binaphthyl] -2,2' -dicarboxylic acid, 4,4 '-bis [ (2-methoxy-6-carboxyl-1-naphthyl) carbonyl] -, tetrabutyl ester (9CI) ", which is affected by the environment a lot.
The first to bear the brunt is the temperature. If the temperature is too high, the molecular thermal motion intensifies, the structure or biological changes of the compound, its stability is damaged, and even decomposition reactions occur, causing it to lose its original characteristics. On the contrary, if the temperature is too low, the molecular activity decreases, and some reactions that depend on molecular motion slow down, or they appear solid at low temperatures, limiting their interaction with other substances.
Humidity should not be underestimated. If this substance is in a high humidity environment, water molecules are easy to interact with it. Water molecules may form hydrogen bonds with polar groups in the compound, which affects the intermolecular forces, changes the crystal structure, or causes changes in its solubility. In severe cases, the presence of water triggers a hydrolysis reaction, destroys key chemical bonds in the molecule, and causes the compound to deteriorate.
The effect of light is also significant. Light of a specific wavelength has sufficient energy, or causes intramolecular electron transitions. If the light energy is appropriate, it can break chemical bonds and initiate photochemical reactions. If the compound is photolyzed, new products will be formed, which will change its chemical composition and properties, affecting its application in materials, medicine and other fields.
In addition, the surrounding medium also has an effect on it. If placed in different solvents, due to differences in the interaction between solvents and compounds, their solubility and dispersibility are different. In some organic solvents, or due to solvation, a specific molecular conformation is stabilized; in another solvent, it may promote molecular aggregation and affect its properties. And when coexisting with other chemical substances, or a chemical reaction occurs, changing its chemical structure and properties.
