What is the chemical property of the product'Benzenesulfonamide, 2-Bromo-4-Fluoro- '?
This is 2-bromo-4-fluorobenzenesulfonamide, which has unique chemical properties. In terms of its physical properties, it may be a solid under normal conditions. Due to the structure of the benzene ring, its melting point and boiling point are affected by the stable structure of the benzene ring. Generally speaking, the melting point is relatively high, and higher energy is required to destroy the lattice structure to make it melt; the boiling point is also high, and the intermolecular force is relatively large.
From the perspective of chemical activity, the introduction of bromine and fluorine atoms on the benzene ring greatly changes the distribution of its electron cloud. Bromine atoms have a certain electron-withdrawing property, and fluorine atoms have extremely strong electronegativity and significant electron-withdrawing effects. In this way, the electron cloud density of the benzene ring decreases, and the electrophilic substitution For example, compared to benzene, when it undergoes electrophilic substitution reactions such as halogenation and nitrification, the reaction conditions may be more severe, requiring higher temperatures and stronger catalysts.
However, the sulfonamide group (-SO 2O NH 2O) endows this compound with unique reactivity. The hydrogen on the nitrogen atom of sulfonamide has a certain acidity and can react with strong bases to form corresponding salts. And sulfonamide groups can participate in a variety of organic reactions, such as condensation reactions with alters, ketones, etc., to form nitrogen-containing heterocycles or other functional compounds. The chemical properties of this compound are determined by its unique structure. In the field of organic synthesis, due to these special properties, it can be used as a key intermediate to construct more complex organic molecular structures to prepare compounds with specific biological activities or material properties.

What is the synthesis method of this product'Benzenesulfonamide, 2-Bromo-4-Fluoro- '?
In order to prepare "Benzenesulfonamide, 2 - Bromo - 4 - Fluoro-", the synthesis method is quite complicated, and strict steps and conditions need to be followed.
First, it is necessary to find suitable starting materials. It is often based on compounds containing benzene rings, such as specific halogenated benzenes, which are often key starting materials in organic synthesis.
Second, for the introduction of bromine and fluorine, it is necessary to use a delicate chemical reaction. Introduce bromine atoms, or use brominating reagents, such as liquid bromine, with the help of catalysts, to make bromine reactions occur at specific positions of the benzene ring. The introduction of fluorine atoms, or by means of nucleophilic substitution reaction, reacts with fluorine-containing reagents with precursors. However, this process requires precise control of the reaction conditions, such as temperature and solvent selection.
Furthermore, the construction of sulfonamide structure is also key. Or first derive the benzene ring into a sulfonic acid compound, and then react with ammonia or amine substances to form a sulfonamide structure. In this process, the activity and selectivity of the reaction are extremely important to prevent unnecessary side reactions.
During the entire synthesis process, the products of each step of the reaction need to be carefully separated and purified, such as column chromatography, recrystallization, etc., to ensure the purity of the products and lay a good foundation for the next reaction. And the reaction conditions of each step, such as temperature, pressure, reaction time, etc., need to be repeatedly debugged and optimized to obtain the ideal yield and purity, and achieve the synthesis of "Benzenesulfonamide, 2 - Bromo - 4 - Fluoro -".
What is the price range of the product'Benzenesulfonamide, 2-Bromo-4-Fluoro- 'in the market?
I don't know the price range of "Benzenesulfonamide, 2 - Bromo - 4 - Fluoro -" in the market. This is a fine chemical, and its price often varies due to many factors.
First, the purity has a great impact. If the purity is very high, it is close to scientific research grade, and it is used for precision experiments, its price will be high; if it is industrial grade, the purity is slightly lower, and the price may drop.
Second, the supply and demand relationship causes price fluctuations. If the market demand for this product is strong and the supply is limited, the price will rise; if the demand is weak and the supply is sufficient, the price may decline.
Third, the complexity of the production process is also related to the price. If the production requires special technology, strict conditions, high cost and high price; if the process is relatively simple, the cost will drop, and the price may be close to the people.
Fourth, different merchants have different pricing. Large merchants may have different pricing from small merchants due to scale effects, brand advantages, and transportation costs, sales regional differences, etc., can all affect the price.
Although I have not found the exact price range, if you want to know, you can go to the chemical product trading platform, consult suppliers or industry insiders, and you will be able to get more accurate details.
