Product Description:

Sodium p-toluenesulfinate is an organosulfur compound with the chemical formula CH₃C₆H₄SO₂Na. It is a white to off-white crystalline powder that is soluble in water and polar organic solvents. This compound serves as a versatile and important reagent in organic synthesis. Its primary application is as a source of the p-toluenesulfonyl (tosyl) anion, which acts as a mild and efficient nucleophile. It is widely used in sulfonylation reactions, Michael additions, and as a key building block for the synthesis of sulfones and other sulfur-containing compounds. It is also employed in radical reactions and as a reducing agent in specific contexts, such as in the reduction of certain functional groups like azides to amines. Due to its stability, ease of handling, and broad reactivity profile, sodium p-toluenesulfinate is a staple reagent in research laboratories and pharmaceutical chemistry for constructing complex molecular architectures.
