2-Chlorobenzenesulfonyl isocyanate

Description:
2-Chlorobenzenesulfonyl isocyanate, with the CAS number 64900-65-8, is an organic compound characterized by the presence of both a sulfonyl group and an isocyanate functional group. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its purity and storage conditions. It 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. The sulfonyl moiety enhances its electrophilic character, making it useful in various synthetic applications, including the preparation of sulfonamide derivatives. Additionally, 2-chlorobenzenesulfonyl isocyanate is sensitive to moisture and should be handled with care, as it can hydrolyze to form corresponding amines and sulfonic acids. Safety precautions are essential when working with this compound, as it may pose health risks, including irritation to the skin, eyes, and respiratory system. Proper storage in a cool, dry place and the use of personal protective equipment are recommended to mitigate exposure risks.
