Purple Solid. 1-Aminonaphthalene-6-sulfonic acid [119- 79-9]. (5-aminonaphthalene-2-sulfonic acid), 1,6-Cleve’s acid, C10H9NO3S, Mr 223.24, crystallizes from boiling water as plates of the dihydrate. Its sodium, potassium, and calcium salts are all readily soluble in water, but the barium salt is only sparingly soluble. Sulfonation with 10 % oleum yields 1-aminonaphthalene-4,6-disulfonic acid. Caustic fusion gives 5- amino-2-hydroxynaphthalene, and Bucherertype hydrolysis gives 1-hydroxynaphthalene-6- sulfonic acid.
