3,5-Dichlorobenzenesulfonyl chloride

Description:

3,5-Dichlorobenzenesulfonyl chloride, with the CAS number 705-21-5, is an organic compound characterized by its sulfonyl chloride functional group attached to a dichlorobenzene ring. This compound typically appears as a colorless to pale yellow solid and is known for its strong electrophilic properties, making it a useful reagent in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. It is highly reactive, especially with nucleophiles, and can release hydrogen chloride upon hydrolysis, which necessitates careful handling and storage under inert conditions to prevent moisture exposure. The presence of chlorine atoms enhances its reactivity and can influence the compound's solubility in various organic solvents. Additionally, 3,5-Dichlorobenzenesulfonyl chloride is utilized in the pharmaceutical industry and in the synthesis of agrochemicals, but it requires appropriate safety measures due to its corrosive nature and potential health hazards upon exposure.

3,5-Dichlorobenzenesulphonyl chloride

CAS: 705-21-5

3,5-Dichlorobenzenesulphonyl chloride (3,5-DCBS) is a halogenated aromatic compound that can be synthesized by the debromination of 3,5-dichlorobenzene with hydrobromic acid. This compound has been shown to have anticancer activity against cell lines derived from human breast cancer, prostate cancer, and other cancers. It also has potent anticancer activity against tumor cells in animals. The anticancer activity of 3,5-DCBS is due to its ability to inhibit DNA synthesis and to induce apoptosis. 3,5-DCBS may act as an anti-inflammatory agent through inhibition of prostaglandin synthesis.
