CAS 20201-03-0: 2-chloro-4-nitrobenzenesulfonyl chloride

Description: 2-Chloro-4-nitrobenzenesulfonyl chloride, with the CAS number 20201-03-0, is an organic compound characterized by its sulfonyl chloride functional group, which is known for its reactivity in various chemical reactions. This compound features a benzene ring substituted with a chlorine atom at the 2-position and a nitro group at the 4-position, contributing to its electrophilic properties. It is typically a solid at room temperature and is soluble in organic solvents such as dichloromethane and acetone, but is generally insoluble in water due to its hydrophobic aromatic structure. The presence of the sulfonyl chloride group makes it a valuable reagent in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. Additionally, it is important to handle this compound with care, as it can be corrosive and may release toxic gases upon hydrolysis. Proper safety precautions, including the use of personal protective equipment, are essential when working with this substance in a laboratory setting.
