4-(Fluorosulfonyl)benzoyl chloride

Description:
4-(Fluorosulfonyl)benzoyl chloride, with the CAS number 402-55-1, is an organic compound characterized by the presence of both a benzoyl chloride and a fluorosulfonyl functional group. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its purity and temperature. It is known for its reactivity, particularly due to the presence of the acyl chloride group, which can readily participate in nucleophilic substitution reactions. The fluorosulfonyl group enhances its electrophilic character, making it a useful intermediate in organic synthesis, particularly in the preparation of sulfonamide derivatives and other fluorinated compounds. Additionally, this compound is sensitive to moisture and should be handled with care, as it can release toxic gases upon hydrolysis. Its applications are often found in pharmaceuticals and agrochemicals, where it serves as a building block for more complex molecules. Proper safety precautions, including the use of personal protective equipment, are essential when working with this substance due to its corrosive and potentially hazardous nature.
