Chemische Eigenschaften
Gray needles, white when pure. Soluble in hot water; sparingly soluble in cold water. 2-Amino-5-hydroxynaphthalene-7-sulfonic acid [87-02-5]. (7-amino-4-hydroxynaphthalene-2-sulfonic acid), J acid, C10H9NO4S, Mr 239.2, is only slightly soluble (0.1 %) in cold water but readily soluble at 100℃. The alkalimetal salts are readily soluble in water. Diazo compounds are normally coupled with J acid under alkaline conditions with reaction in the 6-position (ortho to hydroxyl); however, under acid conditions, coupling can occur in the 1- position. Reaction with bisulfite gives 4,7-dihydroxynaphthalene-2-sulfonic acid. The N-acylation, Nalkylation, and N-arylation reactions are important.
Verwenden
Azo dye intermediate.
Definition
