Benzenemethanesulfonyl chloride

Description:

Benzenemethanesulfonyl chloride, also known as benzylsulfonyl chloride, is an organic compound characterized by the presence of a benzyl group attached to a sulfonyl chloride functional group. It is typically a colorless to pale yellow liquid with a pungent odor. This compound is highly reactive, particularly due to the sulfonyl chloride moiety, which makes it a useful reagent in organic synthesis, especially for the introduction of sulfonyl groups into various substrates. It is soluble in organic solvents such as dichloromethane and ether but is not soluble in water. Benzenemethanesulfonyl chloride is sensitive to moisture and can hydrolyze to form benzenemethanesulfonic acid, releasing hydrochloric acid in the process. Due to its reactivity, it should be handled with care, using appropriate safety measures, as it can cause severe irritation to the skin, eyes, and respiratory tract. Its applications include use in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals, where it serves as an important building block in the development of sulfonamide derivatives.
