4-Iodobenzenesulfonyl chloride

Description:
4-Iodobenzenesulfonyl chloride, with the CAS number 98-61-3, is an organic compound characterized by the presence of both a sulfonyl chloride group and an iodine atom attached to a benzene ring. It appears as a white to light yellow crystalline solid and is known for its reactivity, particularly due to the sulfonyl chloride functional group, which can undergo nucleophilic substitution reactions. This compound is soluble in organic solvents such as dichloromethane and chloroform but is generally insoluble in water. It is often used as a reagent in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. Additionally, the presence of iodine enhances its utility in various coupling reactions and as a potential electrophile in synthetic pathways. However, it should be handled with care due to its corrosive nature and potential health hazards, including irritation to the skin and respiratory system. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound.
