Product Description:

Benzenesulfonamide is an organic compound with the molecular formula C₆H₇NO₂S. It is a white crystalline solid and serves as the simplest aromatic sulfonamide. Structurally, it consists of a benzene ring attached to a sulfonamide functional group (-SO₂NH₂). This compound is a fundamental building block and versatile reagent in synthetic organic chemistry. Its primary role is as a precursor for the synthesis of a wide variety of substituted sulfonamides, which are key structural motifs in pharmaceuticals (e.g., diuretics, sulfa drugs), agrochemicals, and dyes. The sulfonamide group can act as a directing group in metal-catalyzed cross-coupling reactions and is also used as a protective group for amines. Additionally, benzenesulfonamide derivatives are investigated for their biological activities, including carbonic anhydrase inhibition. Benzenesulfonamide is commercially available and commonly used in research and industrial settings for method development and as a starting material. It is generally stable under standard conditions but should be handled with appropriate precautions to avoid inhalation or contact.
