4-Fluoro-3-nitrobenzenesulfonamide, this is an organic compound. Its unique chemical properties allow me to elaborate.
First of all, its structure, above the benzene ring, the fluorine atom and the nitro group live in a specific position, and there are sulfonamide groups connected. This structure creates its unique chemical activity.
In terms of reactivity, although fluorine atoms have strong electronegativity, which reduces the electron cloud density of the benzene ring, due to the strong electron-absorbing effect of the ortho-nitro group, the electron cloud distribution of the benzene ring is more uneven. In this case, the electrophilic substitution reactivity on the benzene ring is greatly changed. The electrophilic substitution of aromatic rings, such as halogenation, nitrification, sulfonation, etc., is affected by fluorine and nitro, and the reaction check point is very different from that of conventional benzene derivatives.
Nitro is a strong electron-absorbing group, which not only affects the reactivity of benzene ring, but also makes the molecule have oxidative properties. Nitro can be reduced to amino groups under specific conditions, which is a commonly used conversion reaction in organic synthesis. The sulfonamide group has a certain acidity, because the hydrogen on the nitrogen atom can leave under the action of appropriate bases to form corresponding salts.
In addition, 4-fluoro-3-nitrobenzenesulfonamide can participate in many condensation reactions. The nitrogen atom of sulfonamide can react with compounds containing active carbonyl groups to form new carbon-nitrogen bonds. This reaction is widely used in the fields of drug synthesis and materials science.
In addition, its solubility also has characteristics. Because the molecule has both polar groups (sulfonamide) and non-polar benzene rings, it has a certain solubility in polar organic solvents such as ethanol and acetone; in non-polar solvents such as n-hexane, the solubility is very small.
The chemical properties of this compound are complex and diverse, and it has important research and application value in organic synthesis, drug development and other fields.

The synthesis of 4-fluoro-3-nitrobenzenesulfonamide is an important topic in the field of chemical synthesis. To synthesize this substance, a common method is to use a compound containing a benzene ring as the starting material.
Take benzene as the initial substrate first, and introduce fluorine atoms and nitro groups by means of an electrophilic substitution reaction. In the electrophilic substitution reaction, a suitable halogenated reagent, such as fluorine gas or a specific fluorine-containing reagent, can be selected. Under appropriate reaction conditions, a fluorination reaction occurs at a specific position on the benzene ring. This process requires fine regulation of reaction temperature, pressure and catalyst to ensure accurate positioning of fluorine atoms.
Then, introduce nitro groups. Mixed acid (a mixture of nitric acid and sulfuric acid) is often used as a nitrifying agent to introduce nitro groups at specific positions on the benzene ring. This step also requires precise control of the reaction conditions to prevent side reactions such as excessive nitrification. At this point, a benzene derivative containing fluorine and nitro groups is obtained.
Subsequently, this derivative is further converted to benzene sulfonamide. Generally, the sulfonation reaction is carried out first, with concentrated sulfuric acid or fuming sulfuric acid as the sulfonating agent, and at a suitable temperature, the sulfonic acid group is introduced on the benzene ring. After that, the sulfonic acid group is converted into sulfonyl chloride. Sulfonyl chloride can be obtained by reacting with sulfonic acid with reagents such as sulfoxide chloride
Finally, the sulfonyl chloride is reacted with ammonia or amine compounds, and 4-fluoro-3-nitrobenzenesulfonamide can be obtained by ammonolysis reaction. This reaction condition is relatively mild, and the yield is considerable. During the whole synthesis process, each step of the reaction needs to strictly control the reaction conditions and carefully purify the intermediate product, so that 4-fluoro-3-nitrobenzenesulfonamide can be effectively and with high purity.

4-Fluoro-3-nitrobenzenesulfonamide is an organic compound. During storage and transportation, many matters need to be paid attention to.
When storing, the first environment should be selected. It should be placed in a cool place, which is easy to change its chemical properties due to high temperature. The temperature should be controlled within a specific range to prevent decomposition or deterioration. And it must be dry, because it may be hygroscopic, the humid environment will make it hygroscopic and affect the quality. Furthermore, it should be placed in a well-ventilated place to avoid the accumulation of harmful gases and cause safety hazards.
This compound may be toxic and corrosive, so the storage place must be kept away from fire and heat sources. Because it may be flammable, there is a risk of combustion and explosion in case of open flames and hot topics. It should also be stored separately from oxidizing agents, reducing agents, etc. to prevent mutual reaction.
During transportation, the packaging should be solid. Make sure that the packaging material can withstand vibration and collision during transportation without leakage. And the packaging should comply with relevant laws and regulations, clearly marked with warning signs to indicate its danger.
Transportation tools are also exquisite, and need to be clean, dry, and free of other substances that may react with them. During transportation, avoid sun and rain, drive according to the specified route, and do not stop in densely populated areas or important places.
In short, when storing and transporting 4-fluoro-3-nitrobenzenesulfonamide, it is necessary to strictly abide by relevant regulations, operate cautiously, and ensure the safety of personnel and the environment from harm.

What you are inquiring about is the market price range of 4-fluoro-3-nitrobenzenesulfonamide. However, the price of this chemical cannot be generalized, and it varies due to many factors.
First, the state of market supply and demand is the main reason. If the demand for this product is strong and the supply is limited, the price will increase; conversely, if the supply is abundant, the demand will be weak, and the price will fluctuate. Second, the cost of production also affects the price. The price of raw materials, the simplicity of the production process, and the amount of energy consumption are all related to the cost. If raw materials are scarce and expensive, or the cost is high due to the complexity of the production process, the price will also rise.
Furthermore, the quality grade is also related to the price. For high purity and high quality, the price is often higher than that of ordinary grades. In addition, regional differences also have an impact. Different places have different prices due to different transportation costs and market competition. In places with developed economies and fierce competition, or low prices due to competition; in remote areas, inconvenient logistics, or high prices due to increased transportation costs.
In summary, the market price range of 4-fluoro-3-nitrobenzenesulfonamide is difficult to specify, ranging from tens of yuan per kilogram to hundreds of yuan. It depends on the above factors. If you want to know the exact price, you should carefully check the market dynamics and relevant supplier quotations.
