2,3-Dichlorobenzenesulfonyl chloride

Description:
2,3-Dichlorobenzenesulfonyl chloride, with the CAS number 82417-45-6, is an organic compound characterized by the presence of both sulfonyl chloride and dichlorobenzene functional groups. It typically appears as a colorless to pale yellow liquid and is known for its reactivity, particularly in nucleophilic substitution reactions. The sulfonyl chloride group (-SO2Cl) makes it a potent electrophile, allowing it to react with various nucleophiles, including amines and alcohols, to form sulfonamides and sulfonate esters, respectively. This compound is often used in organic synthesis, particularly in the preparation of sulfonamide derivatives and as a reagent in the development of pharmaceuticals and agrochemicals. It is important to handle this substance with care, as it can be corrosive and may cause irritation to the skin, eyes, and respiratory system. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this chemical.
