Applications
Description1-Aminonaphthalene-3,6-sulfonic acid [6251-07-6]. (4-aminonaphthalene-2,7- disulfonic acid), Freund’s acid(1,3,6), C10H9NO6S2, Mr 303.3, and its salts are readily soluble in water. Caustic fusion results in a mixture of aminonaphtholsulfonic acids, but amination occurs selectively, producing 1,3-diaminonaphthalene-6-sulfonic acid.
