What is the chemical structure of 4-chloro-3- (5-dihydro-3-methyl-5-oxo-1h-pyrazol-1-yl) -benzenesulfonicaci?
This compound is called 4-chloro-3- (4,5-dihydro-3-methyl-5-oxo-1H-pyrazole-1-yl) benzenesulfonic acid. To clarify its chemical structure, let me explain in detail.
In this structure, the core part is a benzene ring. Above the benzene ring, there is a chlorine atom (-Cl) at position 4. This chlorine atom is a halogen atom substituent. The chlorine atom has a certain electronegativity, which will affect the electron cloud density distribution of the benzene ring and change the reactivity of the benzene ring.
A complex pyrazole derivative group is connected at position 3. The pyrazole ring is 4,5-dihydro-3-methyl-5-oxo-1H-pyrazole-1-yl. The pyrazole ring is a five-membered heterocyclic ring containing two adjacent nitrogen atoms, which has certain aromaticity. At the 4,5 position, it is in the dihydro state, that is, the carbon-carbon double bond on the two positions of the pyrazole ring is in the form of hydrogenation; at the 3 position, there is a methyl (-CH 🥰) substitution, and the methyl group is the power supply group, which will contribute to the electron cloud density of the pyrazole ring; at the 5 position, it is a carbonyl group (-C = O). The oxygen atom in the carbonyl group has strong electronegativity, which will cause the electron cloud of the pyrazole ring to shift to carbonyl oxygen. The pyrazole ring is connected to the benzene ring through the nitrogen atom at the 1st position.
In addition, the benzene ring is also connected with a sulfonic acid group (-SO-H), which is a strong acidic group and has good water solubility. The sulfur atom in the sulfonic acid group is connected to three oxygen atoms, one of which is connected to the sulfur in the form of a double bond, and the other two oxygen atoms are each negatively charged to form a sulfonic acid structure with the hydrogen atom.
In summary, the chemical structure of 4-chloro-3- (4,5-dihydro-3-methyl-5-oxo-1H-pyrazole-1-yl) benzenesulfonic acid is composed of a benzene ring, a chlorine atom, a specific pyrazole derivative group, and a sulfonic acid group. Each part interacts to give the compound its unique chemical properties.

What are the synthesis methods of 4-chloro-3- (5-dihydro-3-methyl-5-oxo-1h-pyrazol-1-yl) -benzenesulfonicaci
There are several ways to synthesize 4-chloro-3- (4,5-dihydro-3-methyl-5-oxo-1H-pyrazole-1-yl) -benzenesulfonic acid. First, it can be obtained by nucleophilic substitution reaction of benzenesulfonic acid derivatives with specific substituents and precursors containing pyrazole structures under suitable reaction conditions. To perform this reaction, first take an appropriate amount of benzenesulfonic acid derivatives, whose chlorine atoms need to be in a specific position, which is the activity check point of subsequent reactions. At the same time, compounds containing 4,5-dihydro-3-methyl-5-oxo-1H-pyrazole-1-yl are prepared. The synthesis of this compound also needs to follow specific steps, or through multi-step reactions to construct pyrazole rings and introduce methyl and oxo groups.
When both are prepared, place them in a suitable solvent, which needs to be able to dissolve the reactants without interfering with the reaction process, such as some polar organic solvents. Adding a suitable base, the effect of the base is to promote the generation of nucleophiles and promote the nucleophilic substitution reaction. Control the reaction temperature and time. If the temperature is too high or too low, the reaction rate and product selectivity may be affected. If the time is too short, the reaction will be incomplete, and if it is too long, side reactions may be triggered. After careful regulation, the two can fully react to form the target product 4-chloro-3- (4,5-dihydro-3-methyl-5-oxo-1H-pyrazole-1-yl) -benzenesulfonic acid.
In addition, there are other synthesis paths. The connection structure of benzene ring and pyrazole ring can be constructed first, and then the sulfonic acid group and chlorine atom can be introduced. This principle requires a delicate design of the reaction sequence and conditions, introducing each group one after another according to the activity and selectivity of different reactions. Or use some special catalysts to improve the reaction efficiency and selectivity, but this process requires precise control of the type, dosage and reaction environment of the catalyst to achieve the ideal synthesis effect. In short, the synthesis of this compound requires comprehensive consideration of various factors such as the characteristics of the reactants, reaction conditions and the purity of the expected product, and the most suitable synthesis method is selected.
