o-Bromobenzenesulfonyl chloride

Description:

o-Bromobenzenesulfonyl chloride, with the CAS number 2905-25-1, is an organic compound characterized by the presence of a bromobenzene ring and a sulfonyl chloride functional group. It typically appears as a colorless to pale yellow liquid or solid, depending on its purity and storage conditions. This compound is known for its reactivity, particularly due to the sulfonyl chloride group, which can participate in nucleophilic substitution reactions. It is often used as a reagent in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. The presence of the bromine atom enhances its electrophilic character, making it a useful intermediate in various chemical transformations. o-Bromobenzenesulfonyl chloride is sensitive to moisture and should be handled with care, as it can release hydrochloric acid upon hydrolysis. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound due to its corrosive nature and potential health hazards.

2-Bromobenzene sulfonyl chloride

CAS: 2905-25-1

2-Bromobenzene sulfonyl chloride is a halide that reacts with electron-deficient molecules to form electrophilic bromonium ions. These electrophiles react with nucleophiles in biological systems to form covalent adducts. The reaction can be carried out in the presence of oxygen or in an inert atmosphere, and the product can be isolated by extraction or distillation. 2-Bromobenzene sulfonyl chloride has been found to be an efficient method for the synthesis of biomolecules, such as proteins and peptides, using arylation reactions. This agent also has cell-specific properties and is toxic to BV2 microglial cells but not PC3 cells.
