207974-14-9 - Introduction
4-Bromo-2, chloride is an organic compound with the chemical formula C6H2BrF2ClO2S. The following is a description of its nature, use, preparation and safety information:
Nature:
4-Bromo-2, chloride is a white solid. It has a strong odor and is soluble in organic solvents such as ethanol and dimethylformamide, but insoluble in water. It is a strong oxidant and corrosive.
Use:
4-Bromo-2, chloride is widely used in organic synthesis. It is commonly used as a sulfonyl chloride reagent and plays an important role in organic chemical reactions, such as esterification, etherification, and acylation. It is also used in the preparation of drugs, dyes and polymer materials.
Method:
4-Bromo-2, chloride is generally obtained by reacting 4-Bromo-2, 5-fluorobenzenesulfonyl chloride with chloroacetic acid under appropriate conditions. The specific preparation method can refer to the literature of organic synthetic Chemistry and Laboratory Manual.
Safety Information:
Because 4-Bromo-2, chloride is oxidizing and corrosive, safety measures should be taken when using it. It may cause irritation and corrosion to the eyes, skin and respiratory tract, so direct exposure should be avoided. Wear appropriate personal protective equipment such as glasses, gloves and protective clothing during use and preparation. In addition, it should be operated in a well-ventilated place to avoid inhaling its vapors. If exposed or inhaled, rinse immediately with plenty of water and seek medical help.
