What are the physical properties of 4-chloro-3- (3-methyl-5-oxo-2-pyrazolin-1-yl) benzenesulfonic Acid
4-Chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid, which is an organic compound. Looking at its physical properties, under normal conditions, it is mostly solid. Because its molecular structure contains sulfonic acid groups, this group has strong hydrophilicity, so the compound should have a certain solubility in water. And because there are many polar groups in the molecule, the intermolecular force is strong, and the melting point may be relatively high, requiring a higher temperature to melt it.
Its appearance may be white to light yellow crystalline powder, which is due to the conjugated system and substituents in the molecular structure affecting the absorption and reflection of light. As for the odor, because it is not a highly volatile substance, or only has a weak special odor.
In terms of density, because the molecule contains relatively large atoms such as chlorine atoms, and the structure is relatively compact, its density may be greater than that of common organic solvents. In addition, the stability of the compound cannot be ignored. Due to the relatively stable structure of the pyrazoline ring and benzene ring in the molecule, under normal conditions, without special reagents or conditioned stimulation, its chemical properties are relatively stable, and it is not easy to spontaneous decomposition or other violent reactions. However, when encountering specific reagents such as strong acids, strong bases, or strong oxidants, some chemical bonds in the molecular structure may be affected, leading to corresponding chemical reactions.

Is 4-chloro-3- (3-methyl-5-oxo-2-pyrazolin-1-yl) benzenesulfonic acid chemically stable?
4-Chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid, this is an organic compound. Looking at its chemical properties, stability is an important consideration.
Under normal circumstances, such compounds containing benzenesulfonic acid structure have certain stability due to the electronic effect of the conjugate system of the benzene ring and the sulfonic acid group. The benzene ring conjugate system endows the molecular structure with certain rigidity and stability. The sulfonic acid group is a strongly acidic group, and its existence can make the compound exhibit acid-related chemical reactions under specific conditions, but its own structure is relatively stable.
However, this compound still contains chlorine atoms and pyrazolone structures. Chlorine atoms can be changed by reactions such as nucleophilic substitution. In the structure of pyrazolone, carbonyl (5-oxo) is connected to pyrazole ring, which gives the structure a certain reactivity. The pyrazole ring has electron-rich properties and can participate in reactions such as electrophilic substitution; the presence of carbonyl makes the pyrazolone part vulnerable to nucleophilic attack and reactions such as addition.
The stability of 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid may be affected if it is in a specific chemical environment, such as high temperature, strong acid base or the presence of a specific catalyst. Under high temperature, the chemical bond may be broken, resulting in structural changes; the strong acidic environment may affect the protonation state of the pyrazolone structure and change its reactivity; under strong basic conditions, the chlorine atom may undergo nucleophilic substitution, sulfonic acid groups or neutralization with bases.
In summary, the stability of 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid is not absolute, and it may be relatively stable at room temperature and general environment. However, under special chemical conditions, its structure and properties may change.

What are the synthesis methods of 4-chloro-3- (3-methyl-5-oxo-2-pyrazolin-1-yl) benzenesulfonic Acid
There are several ways to synthesize 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid.
First, we can start from chlorobenzenesulfonic acid derivatives. First, introduce chlorine atoms at specific positions in the benzene ring with suitable chlorination reagents to obtain chlorobenesulfonic acid. Then, the chlorobenesulfonic acid is reacted with 3-methyl-5-oxo-2-pyrazoline derivatives. This reaction needs to be carried out in a suitable solvent, such as a polar organic solvent, such as dimethylformamide (DMF) or dichloromethane, and a suitable base, such as potassium carbonate or triethylamine, should be added to promote the reaction. The base can assist the pyrazoline derivative to form an active intermediate, and then undergo a nucleophilic substitution reaction with chlorobenzenesulfonic acid to form the target product.
Second, it can also be started from 3-methyl-5-oxo-2-pyrazoline-1-ylbenzene derivatives. The benzene ring of this derivative is first sulfonated. Generally, concentrated sulfuric acid or fuming sulfuric acid can be used as the sulfonating agent, and the benzene ring can be introduced into the sulfonic acid group under appropriate temperature conditions. Subsequently, the obtained product is chlorinated. In the chlorination process, chlorine gas, thionyl chloride and other chlorinated reagents can be selected. Under the catalysis of suitable catalysts, such as iron powder or ferric chloride, chlorine atoms are introduced into the designated position of the benzene ring to obtain 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzene sulfonic acid.
Furthermore, it can be synthesized by the strategy of constructing pyrazoline rings. First, the precursor of pyrazoline ring containing chlorobenzenesulfonyl is prepared. For example, chlorobenzenesulfonyl chloride is reacted with suitable hydrazine derivatives and acetylacetone compounds under specific conditions. Usually in an alcohol solvent, such as ethanol, it is heated and refluxed to make the three cyclize to form a pyrazoline ring, and the structure of the target product is constructed, namely 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid. Each synthesis method has its own advantages and disadvantages, and a suitable synthesis path needs to be selected according to the actual situation, such as the availability of raw materials, the ease of control of reaction conditions, etc.

What is the price range of 4-chloro-3- (3-methyl-5-oxo-2-pyrazolin-1-yl) benzenesulfonic Acid in the market?
4-Chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid, a chemical substance in the field of fine chemicals. On the market, its price range changes are quite complex and influenced by many factors.
The first to bear the brunt, the difficulty of the preparation process has a significant impact on its price. If the preparation of this compound requires complicated steps, harsh reaction conditions, such as specific catalysts, precise temperature and pressure control, and limited yield, it will inevitably lead to high production costs and rising prices. On the contrary, if the process is simple and efficient, the cost can be reduced, and the price will be more accessible to the people.
Furthermore, the price fluctuation of raw materials is also a key factor. If the supply of raw materials is tight, difficult to obtain, or affected by the imbalance between market supply and demand, or the sudden situation of origin, the price of raw materials will rise, which in turn will drive up the price of 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid.
Market demand conditions also affect its price. If this compound is in strong demand in downstream industries such as pharmaceuticals, pesticides, and dyes, and the supply is in short supply, the price will naturally rise. On the contrary, if the demand is weak and the market competition is fierce, the price may face downward pressure.
In addition, the purity standard of the product is also closely related to the price. High-purity products, because of their difficulty in production and strict quality control, can meet the needs of high-end fields, so the price is much higher than that of ordinary purity products.
In summary, in the current market, the price of 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid is difficult to accurately determine without specific market survey data. However, it is roughly estimated that ordinary purity products range from a few hundred yuan to several thousand yuan per kilogram; high purity products range from several thousand yuan per kilogram to even higher, depending on the actual market conditions.
