What is Naphthol-4-sulfonic Acid?

Naphthol-4-sulfonic acid is an organic compound belonging to the family of naphthalene derivatives. Its chemical structure, featuring a hydroxyl and a sulfonic acid group on the naphthalene core, makes it an excellent coupling agent in azo dye production. This reactivity allows it to react with diazonium salts to form azo compounds, which are the chromophores responsible for the color in dyes and pigments. Its typical form is a grayish-white powder, easily soluble in water, which is advantageous for many industrial processes. It is a critical building block for dyes like Direct Copper Blue BR and 2R, Direct Purple RB, Acid Red B, and Acid Medium Bordeaux B.
