2-Fluorobenzenesulfonamide is one of the organic compounds. Its physical properties are interesting and worthy of careful investigation.
First of all, its appearance is usually white to white crystalline powder, which is delicate and uniform, like the condensation of frost and snow, and has a sense of purity. This form is conducive to observation and identification, and is also convenient for subsequent processing and application.
As for the melting point, it is about 138 ° C to 142 ° C. The characteristics of the melting point are like the "individual temperature" of the substance. In this temperature range, the solid 2-fluorobenzenesulfonamide begins to melt into a liquid state. This change reveals the characteristics of its intermolecular forces, which is of great significance for substance identification and purity judgment.
Solubility is also an important physical property. 2-Fluorobenzenesulfonamide is slightly soluble in water, just like a "reserved" guest, and only has limited fusion in water. However, it is soluble in common organic solvents such as ethanol and acetone. In ethanol, its molecules are like "confidants", and can be evenly dispersed, showing good solubility. This difference in solubility is due to the difference in its molecular structure and the interaction between water molecules and organic solvent molecules, which is a key consideration in chemical synthesis, separation and purification operations.
In addition, its density also has a specific value. Although accurate data needs to be professionally determined, this physical quantity is related to its distribution in the mixture and has a great impact on chemical production and experimental operations.
In addition, the stability of 2-fluorobenzenesulfonamide is acceptable at room temperature and pressure. However, in case of high temperature, open flame or strong oxidant, its molecular structure may be affected, triggering chemical reactions. This characteristic requires special attention during storage and transportation, and appropriate conditions must be used to ensure its quality and safety.
Overall, the physical properties of 2-fluorobenzenesulfonamide are diverse and unique, and each property is interrelated, which is of great value in chemical research, industrial production and related fields.

2-Fluorobenzenesulfonamide is also an organic compound. Its properties are related to various chemical properties, and it is quite important in the chemical industry, medicine and other industries.
Looking at its physical properties, at room temperature, it is mostly solid, and the color is often nearly white, in a powdery or crystalline state. Its melting point and boiling point vary depending on the interaction between fluorine and sulfonamide groups in the molecular structure. The introduction of fluorine atoms changes the force between molecules, causing the melting point to change. Generally speaking, the melting point is within a specific range, and it can be accurately measured by the method of melting point determination.
As for its chemical properties, sulfonamide groups are weakly acidic and can react with bases to form corresponding salts. This is because the hydrogen on the nitrogen atom is affected by the electron-withdrawing effect of the sulfonyl group and has a certain tendency to dissociate. The fluorine atom on the benzene ring, although relatively stable, can also participate in the substitution reaction under specific conditions. In case of strong nucleophilic reagents, fluorine atoms may be replaced. Due to the electron cloud density of the ortho and para-position of fluorine atoms, it is affected by the conjugation system of the benzene ring and the electronegativity of the fluorine atom, which changes, making nucleophilic reagents easy to attack.
And because of its sulfonamide structure, it can participate in many organic synthesis reactions, such as reacting with alcohols, amines and other compounds to construct new compounds. It is an important synthetic building block in the creation of drug molecules, functional materials and other fields. The presence of fluorine atoms endows it with unique biological activity and stability. In pharmaceutical research and development, it can change the pharmacokinetic properties of compounds, increase their bioavailability, or change the ability of compounds to bind to biological targets, thereby optimizing drug efficacy.
In summary, 2-fluorobenzenesulfonamide has its special chemical structure and diverse and unique chemical properties, which is of great significance in the development of modern chemistry and related industries.

The synthesis methods of 2-fluorobenzenesulfonamide are generally as follows.
First, 2-fluorobenzenesulfonic acid is used as the starting material to react with ammonia. First, in a suitable reaction vessel, put 2-fluorobenzenesulfonic acid, slowly add liquid ammonia, or pass ammonia into its solution. This process needs to pay attention to the reaction temperature, which is usually controlled at low temperature to prevent side reactions from breeding. Because 2-fluorobenzenesulfonic acid is acidic and ammonia is alkaline, the two meet, the acid and base are neutralized, and after forming a salt, 2-fluorobenzenesulfonamide can be obtained by appropriate treatment, such as heating and dehydration. The reaction mechanism is that the sulfonic acid group is substituted with the amino group of ammonia, and the hydroxyl group of the sulfonic acid group is replaced by the amino group, so as to achieve the target product.
Second, starting from 2-fluoroaniline. First, use an appropriate sulfonation reagent, such as fuming sulfuric acid, to interact with 2-fluoroaniline. The fuming sulfuric acid contains excess sulfur trioxide, which can be electrophilically substituted with the phenyl ring carbon atom of the amino ortho-position of 2-fluoroaniline to introduce the sulfonic acid group. After the reaction is completed, the sulfonic acid group is converted into sulfonyl chloride through steps such as neutralization and separation. Then the sulfonyl chloride is treated with ammonia, and the amino nucleophilic group in the ammonia attacks the carbonyl carbon of the sulfon In this path, the sulfonation step needs to precisely control the reaction conditions, temperature, and reagent ratio are all critical, otherwise it is easy to cause side reactions such as polysulfonation.
Third, 2-fluorobenzoic acid is used as the starting material and synthesized through multi-step reaction. First, 2-fluorobenzoic acid is converted into the corresponding acid chloride, and reagents such as thionyl chloride are commonly used. The acid chloride reacts with thiourea to form an intermediate. This intermediate is hydrolyzed and oxidized to obtain 2-fluorobenzenesulfonic acid, and then reacts with ammonia to obtain 2-fluorobenzenesulfonamide according to the first method. Although this synthesis method is slightly complicated, the raw materials are easily available, and the reaction selectivity of each step can be adjusted, which is also a feasible path under specific circumstances.
All this synthesis method has its own advantages and disadvantages, and it needs to be selected according to many factors such as raw material availability, cost, yield and purity.

2-Fluorobenzenesulfonamide is on the market, and its price range is difficult to determine. The price of this substance often varies for various reasons.
First, it is related to the cost of production. If the raw materials required for the production of 2-fluorobenzenesulfonamide are expensive, or difficult to obtain, or the preparation process is complicated, requiring a lot of manpower, material resources and energy, the price of the finished product will also be high. If the origin of the raw materials is far and near, the price can fluctuate.
Second, it depends on the supply and demand of the market. If the market demand for 2-fluorobenzenesulfonamide is strong, but the supply is small, the price will rise; on the contrary, if the supply exceeds the demand, the price may drop in order to sell the goods. Such as changes in demand in the pharmaceutical, chemical and other industries can affect the market price.
Third, it is related to the brand and quality of the manufacturer. Manufacturers with good reputation and excellent quality may have higher prices than other factories. Because their products are purer and have better performance, they can give users better results, so users may be willing to pay a high price to buy them.
Fourth, the impact of policies, regulations and taxes cannot be ignored. If the government imposes strict regulations on the relevant industries, or increases taxes, the cost of the manufacturer will increase, and the price will also increase.
According to past examples and market conditions, the price of 2-fluorobenzenesulfonamide may range from tens to hundreds of yuan per kilogram. However, this is only an approximate number, and the actual price still needs to be consulted with the supplier, depending on the current specific situation.
