Sodium 3-nitrobenzenesulfonate (Cat No.: R027051) is an aromatic sulfonate salt featuring a nitro group at the meta (3-) position of the benzene ring. It is commonly used as an intermediate in dye, pigment, and pharmaceutical synthesis. The sulfonate group imparts high water solubility, making it useful in aqueous reactions and formulations. Its electron-withdrawing nitro and sulfonate groups activate the aromatic ring for further substitution reactions. This compound also serves as a reagent in organic transformations and as a precursor in sulfonation chemistry.
