2-oxo-2,3-dihydro-1H-benzimidazole-5-sulfonyl chloride

Description:
2-Oxo-2,3-dihydro-1H-benzimidazole-5-sulfonyl chloride, with the CAS number 53439-87-5, is a chemical compound characterized by its sulfonyl chloride functional group, which makes it a reactive intermediate in organic synthesis. This compound features a benzimidazole core, which is a bicyclic structure containing both benzene and imidazole rings. The presence of the sulfonyl chloride group indicates that it can participate in nucleophilic substitution reactions, making it useful for the synthesis of sulfonamides and other derivatives. It is typically a solid at room temperature and may be sensitive to moisture, as sulfonyl chlorides can hydrolyze to form sulfonic acids. The compound is often handled with care due to its potential reactivity and the release of hydrochloric acid upon reaction. Its applications are primarily found in pharmaceutical chemistry and materials science, where it serves as a building block for more complex molecules. Proper safety measures should be taken when working with this compound due to its corrosive nature.
