Bis(chlorosulfonyl)diphenyl ether (CAS 121-63-1) is a chemical compound with distinct properties that dictate its handling and application. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of understanding these characteristics to ensure safe and effective use of this vital intermediate.

Chemically, Bis(chlorosulfonyl)diphenyl ether is characterized by its diphenyl ether backbone substituted with two chlorosulfonyl groups at the para positions. This structural feature imparts significant reactivity, making it susceptible to hydrolysis in the presence of moisture. Consequently, the compound is classified as moisture-sensitive. Its typical appearance is a white to light yellow crystalline powder, and it is soluble in common organic solvents like chloroform, ethyl acetate, ethanol, and methanol, but has limited solubility in water. The melting point is reported to be around 124-127°C.

Given its moisture sensitivity, proper storage and handling are critical. Bis(chlorosulfonyl)diphenyl ether should be stored in tightly sealed containers in a cool, dry environment, preferably under an inert atmosphere to prevent degradation. When handling, appropriate personal protective equipment (PPE) should be worn, including chemical-resistant gloves, safety goggles, and protective clothing, to avoid contact with skin and eyes. Inhalation of dust or vapors should also be prevented by working in a well-ventilated area or using respiratory protection.

The reactivity of the chlorosulfonyl groups makes Bis(chlorosulfonyl)diphenyl ether a valuable intermediate in various chemical syntheses. As discussed previously, its primary industrial application is in the production of OBSH foaming agents. Its role in organic synthesis and potential pharmaceutical applications also stems from the reactivity of these functional groups. Understanding the 4,4'-Bis(chlorosulfonyl)diphenyl ether production and its reaction mechanisms is key for chemists working with this compound.
