C6H5SO2Na

C6H5SO2Na, also known as sodium benzenesulfinate, is an organic salt with the chemical formula C6H5SO2Na. It is the sodium salt of benzenesulfinic acid. This compound typically appears as a white to off-white crystalline solid. It is soluble in water and moderately soluble in polar organic solvents like ethanol.

Sodium benzenesulfinate plays a role as a reducing agent in various organic synthesis reactions. It can be used to introduce a phenylsulfonyl group into organic molecules. For instance, it is a precursor in the synthesis of other organosulfur compounds. It can also participate in nucleophilic substitution reactions.

In some applications, sodium benzenesulfinate is used as an additive or intermediate in the production of dyes and pharmaceuticals. Its reactivity stems from the benzenesulfinate anion, which can act as a nucleophile or be oxidized. While generally considered stable under normal conditions, it should be stored in a cool, dry place away from strong oxidizing agents.
