2-Hydroxynaphthalene- 4 -sulfonic acid [6357-85-3]. (3-hydroxynaphthalene-1- sulfonic acid), C10H8O4S, Mr 224.2, and its salts are extremely soluble in water and difficult to isolate. It undergoes nitrosation and couples with diazo compounds in the 1-position. Sulfonation with oleum gives 2-hydroxynaphthalene-4,8-disulfonic acid. Amination with ammonia under pressure gives 2-aminonaphthalene-4-sulfonic acid.
