(4-methylphenyl)methanesulfonyl chloride

Description:
(4-Methylphenyl)methanesulfonyl chloride, also known as p-tolylmethanesulfonyl chloride, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a methanesulfonyl moiety and a para-methylphenyl group. 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 a sulfonylating agent. It is commonly used in organic synthesis for the preparation of sulfonamides and other derivatives. The presence of the sulfonyl chloride group makes it a potent electrophile, allowing it to react with various nucleophiles, including amines and alcohols. Additionally, it is important to handle this compound with care due to its corrosive nature and potential to release toxic gases upon hydrolysis. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this chemical.
