Application

6-Aminonaphthalene-1-sulfonic acid serves as a key building block for azo dyes and functionalized heterocycles, offering robust bench stability and excellent solubility in aqueous and polar organic media. Its ortho-directed sulfonic acid group enhances regioselectivity in electrophilic substitution, while the primary amine enables straightforward coupling reactions. The compound functions reliably in diazotization and coupling workflows, facilitating efficient access to dye intermediates and bioactive scaffolds under standard laboratory conditions.
