4-Chlorobenzenesulfonyl isocyanate

Description:
4-Chlorobenzenesulfonyl isocyanate, with the CAS number 5769-15-3, is an organic compound characterized by its sulfonyl and isocyanate functional groups. It appears as a colorless to pale yellow liquid or solid, depending on temperature and purity. This compound is known for its reactivity, particularly in nucleophilic substitution reactions, where it can act as an electrophile due to the presence of the isocyanate group. It is often used in organic synthesis, particularly in the preparation of sulfonamide derivatives and other nitrogen-containing compounds. The presence of the chlorine atom enhances its electrophilic character, making it useful in various chemical transformations. Additionally, 4-chlorobenzenesulfonyl isocyanate is sensitive to moisture and should be handled with care, as it can hydrolyze to form corresponding sulfonic acids and urea derivatives. Proper safety measures, including the use of personal protective equipment, are essential when working with this compound due to its potential toxicity and irritant properties.
