2-Naphthalenesulfonic acid (sodium salt) serves as a versatile sulfonating agent and solubilizing auxiliary in synthetic organic chemistry. Its sodium salt form enhances aqueous solubility, facilitating use in hydrophilic reaction environments. It functions effectively in electrophilic aromatic substitution and as a directing group in transition-metal-catalyzed couplings. The compound exhibits bench stability and compatibility with diverse functional groups, enabling reliable incorporation into complex molecule synthesis, including heterocyclic scaffolds and pharmaceutical intermediates.
