(4-cyanophenyl)methanesulfonyl chloride

Description:
(4-Cyanophenyl)methanesulfonyl chloride, with the CAS number 56105-99-8, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a methylene bridge, which is further substituted with a 4-cyanophenyl 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 sulfonyl chloride group, which can participate in nucleophilic substitution reactions, making it useful in organic synthesis, especially for the introduction of sulfonyl groups into various substrates. The presence of the cyano group enhances its electrophilic character, allowing it to engage in further chemical transformations. Additionally, (4-cyanophenyl)methanesulfonyl chloride is sensitive to moisture and should be handled with care, as it can release hydrochloric acid upon hydrolysis. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound due to its potential irritant properties.
