First view "3- [2- (3-methyl-5-oxo-1-phenyl-1,5-dihydro-4H-pyrazole-4-subunit) hydrazine]", this part contains a pyrazole ring. The pyrazole ring is a five-membered heterocycle composed of two nitrogen atoms and three carbon atoms. Among them, 3-methyl indicates that the 3rd position of the pyrazole ring is connected with methyl; 5-oxo indicates that the 5th position is carbonyl; 1-phenyl refers to the 1st position connected to phenyl; 1,5-dihydro-4H-pyrazole-4-subunit means that the 4th position of the pyrazole ring exists in the form of a subunit and is connected to 2-hydrazine.
Look again at "5-nitro-2-oxidized benzene sulfonate", which is a benzene ring derivative. The 5th position of the benzene ring is connected with a nitro group, and the 2nd position is a benzene sulfonate oxide group. In the sulfonic acid group, the sulfur atom is connected to three oxygen atoms, and one of the oxygen atoms is negatively charged and combines with metal ions or other cations to form salts.
Overall, this compound has a benzene ring as the core, and one side is connected to the hydrazine group containing the pyrazole ring, and the other side is connected to the nitro group and the oxidized benzene sulfonic acid group. This structure endows the compound with unique chemical properties and reactivity, and may have important uses in organic synthesis, pharmaceutical chemistry and other fields.

When it comes to appearance, this chemical is often in a specific form, either crystalline or powder state. Looking at its shape and color, its characteristics can be initially identified. In terms of color, it is either colorless and transparent, or has a slight color, which is caused by the interaction of groups in the molecular structure.
Solubility is also a key physical property. In different solvents, its dissolution performance varies. In polar solvents, hydrogen bonds or other forces can be formed with solvent molecules, or it can show good solubility; in non-polar solvents, due to differences in force, solubility may be poor.
Melting point is also an important physical parameter. The level of melting point is determined by the strength of intermolecular forces. If there are strong interactions between molecules of this substance, such as hydrogen bonds, van der Waals forces, etc., the melting point may be higher; conversely, if the interaction is weaker, the melting point is relatively lower. The determination of the melting point can provide an important reference for its purity and stability.
Density can also not be ignored. Density reflects the mass per unit volume of a substance and is related to the degree of closeness of molecular arrangement. Closely arranged molecular structures often correspond to higher densities. Through the determination of density, its structure and composition can be better understood.
In addition, the stability of this substance is also closely related to physical properties. Properties such as melting point and solubility will affect its stability under different environmental conditions. If the melting point is low, in a slightly higher temperature environment, phase changes may occur easily; poor solubility, in some systems, or it is difficult to disperse uniformly, which affects its stability. The physical properties of this chemical substance, including its appearance, solubility, melting point, density, etc., are interrelated and interact with each other, which is of crucial significance for in-depth understanding of its properties and applications.

To obtain 3 - [2 - (3 - methyl - 5 - oxo - 1 - phenyl - 1,5 - dihydro - 4H - pyrazole - 4 - isyl) hydrazine] -5 - nitro - 2 - oxidized benzenesulfonate, the synthesis method is quite complicated and requires careful handling.
First, all raw materials, such as specific benzenesulfonates, pyrazole derivatives containing specific substituents, etc., must be pure to ensure a smooth reaction.
At the beginning of the reaction, it is often necessary to choose an appropriate solvent, such as organic solvent dimethyl sulfoxide (DMSO) or N, N-dimethylformamide (DMF), which can make the reactants uniformly dispersed and promote full contact.
During the reaction process, temperature control is crucial. Initially, low temperature initiation may be required to slow down the initiation of the reaction, and then gradually heat up to a suitable range to make the reaction progress steadily. Generally speaking, the initial temperature may be 0-10 ° C, and then rise to 40-60 ° C, but the specific temperature must be fine-tuned according to the actual reaction conditions.
Furthermore, the pH of the reaction system cannot be ignored. The pH value can be adjusted by means of buffers to stabilize the reaction environment and ensure that the reaction proceeds according to the expected path.
After the reaction is completed, the separation and purification of the product is also crucial. It is often performed by column chromatography or recrystallization. The column chromatography selects the appropriate stationary phase and mobile phase, which can effectively separate impurities and products; recrystallization uses the different solubility of the product and impurities at different temperatures to achieve the purpose of purification.
Synthesis of this compound requires strict adherence to operating standards and fine control of each reaction element to obtain the ideal yield and purity.
