When it comes to solubility, because the molecule contains disulfonate groups, which are hydrophilic groups, the substance may have a certain solubility in water. However, the molecule also contains more hydrophobic structures of aromatic hydrocarbons, which may limit its solubility in water. In polar organic solvents, such as ethanol, acetone, etc., according to the principle of similarity dissolution, because these solvents can form intermolecular forces with some groups in the molecule, their solubility may be higher than that in water.
Its melting point is also an important physical property. In view of the complexity of the molecular structure, the intermolecular forces are more diverse, including van der Waals forces, hydrogen bonds, and ionic bonds (due to sodium salts). Many forces are intertwined, causing its melting point to be in a higher temperature range. The specific melting point value needs to be accurately determined by experiments. However, it is conceivable that due to the complex and strong intermolecular forces, its melting point may be significantly higher than that of ordinary simple organic compounds.
The density of this compound is also closely related to the structure. Many atoms in the molecule are closely arranged and contain atoms with relatively large atomic mass, such as sulfur, sodium, etc. In addition, the structure is complex and the space occupancy is high, so the density may be relatively large. However, the exact density still needs to be determined by experimental measurement.

(8Z) -7-oxo-8- (2- {4- [ (E) -phenyldiazo] phenyl} hydrazinido) -7,8-dihydronaphthalene-1,3-disulfonate The synthesis method of disodium salt is as follows:
At the beginning, an appropriate amount of naphthalene derivative is taken, and its structure contains a modifiable check point to introduce a sulfonate group appropriately. This step may be required in a specific solvent, such as a polar organic solvent, accompanied by a catalyst, a temperature control reaction, so that the sulfonation reaction is carried out in an orderly manner to obtain a sulfonate-containing naphthalene intermediate.
Then, the phenylhydrazine derivative containing phenyl diazo group is prepared. Starting with aniline compounds, the amino group is converted to diazo groups through diazotization reaction. The conditions need to be carefully controlled, such as the amount of sodium nitrite, the concentration of acid and the reaction temperature. After obtaining the diazo salt, it reacts with the corresponding hydrazine compound to obtain the target phenylhydrazine derivative.
Then, the sulfonate-containing naphthalene intermediate is mixed with the phenylhydrazine derivative, and the pH value is adjusted to a suitable range in a suitable reaction system, such as a buffer solution system, or an adjuvant needs to be added to promote the reaction, and the temperature is raised to an appropriate temperature to cause the condensation reaction between the two to occur, resulting in (8Z) -7-oxo-8- (2- {4- [ (E) -phenyldiazo] phenyl} hydrazinido) -7,8-dihydronaphthalene-1,3-disulfonate.
