(3Z) -5-amino-3- ({4 '- [ (2E) -2- (8-amino-1-oxo-3,6-disulfonate naphthalene-2 (1H) -subunit) hydrazinyl] -3,3' -dimethoxybiphenyl-4-yl} hydrazinyl) -4-oxo-3,4-dihydronaphthalene-2,7-disulfonic acid The synthesis method is as follows:
First, prepare the corresponding starting materials. Naphthalene compounds containing specific substituents, biphenyl compounds, and hydrazines and other reagents need to be prepared to ensure that their purity and quality meet the requirements of the reaction.
The first step is to properly modify the naphthalene compounds. The sulfonic acid group can be introduced at specific positions of the naphthalene ring, such as positions 3 and 6, through a sulfonation reaction to enhance the water solubility and reactivity of the compound. During the reaction, the naphthalene compound is placed in a suitable reaction vessel, an appropriate amount of concentrated sulfuric acid or fuming sulfuric acid is added, and the reaction is reacted at a certain temperature and time. During this period, the reaction process is closely monitored. The change of the raw material point and the product point can be observed by thin-layer chromatography (TLC). When the reaction is completed, the reaction liquid is cooled, carefully poured into ice water, and the sulfonated product is precipitated. The sulfonated naphthalene derivative is filtered, washed, and dried.
The second step is to construct a hydrazine-linked structure. The above sulfonated naphthalene derivative and 8-amino-1-oxonaphthalene-2-one are heated for reflux in the presence of an acidic catalyst with an appropriate organic solvent as the reaction medium. The two are condensed by hydrazine to form intermediates containing specific structures. After the reaction is completed, the reaction solution is distilled under reduced pressure to remove the organic solvent, and the residue is separated and purified by column chromatography to obtain the target intermediate.
The third step is to process the biphenyl compound. The introduction of methoxy at the 3,3 '-position of the biphenyl can be achieved by halogenation reaction, nucleophilic substitution reaction and other steps. The benzene ring is first halogenated to generate halogenated biphenyls, and then reacted with nucleophiles such as sodium methoxide to introduce methoxy groups. After the reaction is completed, the product is separated by extraction, distillation and other means, and further purified by recrystallization.
In the fourth step, the above-mentioned hydrazine-containing naphthalene intermediate is reacted with the modified biphenyl compound under alkaline conditions. Using an appropriate base such as potassium carbonate, sodium carbonate, etc. as a catalyst, in a suitable organic solvent, heating and stirring, a nucleophilic substitution reaction of hydrazine groups occurs to form a key connecting structure. After the reaction is completed, the reaction solution is cooled, and after acidification, precipitation is precipitated, filtered, the filter cake is washed with water, dried, and then recrystallized with an appropriate organic solvent to obtain high-purity (3Z) -5-amino-3- ({4 '- [ (2E) -2- (8-amino-1-oxo-3,6-disulfonate naphthalene-2 (1H) -subunit) hydrazinyl] -3,3' -dimethoxybiphenyl-4-yl} hydrazinyl) -4-oxo-3,4-dihydronaphthalene-2,7-disulfonic acid.
The entire synthesis process requires strict control of reaction conditions, including temperature, time, reactant ratio, catalyst dosage, etc., to ensure the smooth progress of each step of the reaction to improve product yield and purity.

Looking at its structure, it contains many special groups, and its chemical properties are very interesting.
The amino group, sulfonic acid group and hydrazine group in this compound give it specific chemical activities. The amino group is basic and can react with acids under suitable conditions to form salts. The sulfonic acid group is strongly acidic, which can make the compound exhibit good solubility in water and can participate in reactions such as ion exchange. The hydrazine group is not only reductive, but also can be used as a ligand to complex with metal ions due to the lone pair of electrons on the nitrogen atom.
Furthermore, the structure of the naphthalene ring and biphenyl gives the compound a certain rigidity and conjugate system. The conjugate system not only affects the electron cloud distribution, which makes the compound exhibit specific color and spectral properties, but also contributes to its stability. In the fields of photochemistry and electrochemistry, such conjugate structures often exhibit unique properties, such as absorbing and emitting light of specific wavelengths.
From the perspective of reactivity, different groups may interact with each other. For example, the electronic effects of neighboring groups may alter the reactivity of some groups, reducing the activity of an otherwise active check point or making an otherwise inert site more reactive. Such complex structures and diverse groups make this compound potentially useful in many fields, including organic synthesis, materials science, and biomedicine. It can be used to prepare functional materials, or as a biological probe to track specific processes in living organisms.

(This is the name of an extremely complex organic compound. The analysis of its physical properties allows me to elaborate in ancient and elegant words.) This compound can be inferred from the complexity of its structure. It has excellent water solubility because it contains many sulfonic acid groups (-SO and H). Sulfonic acid groups are strongly hydrophilic groups that can form hydrogen bonds with water molecules, so that they can be well dispersed in water.
There are many conjugated systems in its molecules, such as naphthalene rings, biphenyl structures, and conjugated parts containing nitrogen double bonds. This conjugated system may cause it to be absorbed in the visible light region, so it may exhibit a specific color. And the conjugated system also affects the distribution of its electron cloud, so that the molecule has a certain stability.
And because of its large molecular mass and complex interactions between atoms, its melting point may be relatively high. Higher energy is required to overcome the intermolecular forces, so that it changes from a solid state to a liquid state. And its boiling point will also be at a higher level due to strong intermolecular forces, such as hydrogen bonds and van der Waals forces.
In terms of density, due to the tight molecular structure and relatively large atomic weight, its density may be greater than that of common organic solvents. As for its volatility, due to the strong intermolecular forces and relatively large molecules, the volatility is weak.
The physical properties of this compound are determined by its unique molecular structure, and each property is interrelated to present the physical properties of this compound.
