化学的特性1-Amino-8-hydroxynaphthalene-2,4-disulfonic acid [82-47-3]. (4-amino-5-hydroxynaphthalene-1,3-disulfonic acid), Chicago acid, 2 S acid, C10H9NO7S2, Mr 319.3, and its acid sodium salt are readily soluble in water; the latter can be salted out with sodium chloride. In alkaline solution, coupling with diazo compounds takes place ortho to the hydroxyl group. Alkaline hydrolysis at 170℃ gives 1,8-dihydroxynaphthalene-2,4-disulfonic acid. Heating with dilute sulfuric acid results in desulfonation to give 1-amino-8-hydroxynaphthalene-2-sulfonic acid.
