2-Chlorobenzenesulfonyl chloride

Description:

2-Chlorobenzenesulfonyl chloride, with the CAS number 2905-23-9, is an organic compound characterized by the presence of both a sulfonyl chloride group and a chlorine atom attached to a benzene ring. It is typically a colorless to pale yellow liquid that is highly reactive, particularly due to the sulfonyl chloride functional group, which makes it a useful reagent in organic synthesis. This compound is known for its ability to act as a sulfonating agent, facilitating the introduction of sulfonyl groups into various organic molecules. It is also used in the preparation of sulfonamides and other derivatives. 2-Chlorobenzenesulfonyl chloride is soluble in organic solvents such as dichloromethane and ether but is not soluble in water. Due to its reactive nature, it should be handled with care, as it can cause severe irritation to the skin, eyes, and respiratory system. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound.
