2-Aminonaphthalene-1,5,7-trisulfonic acid. (128) (6-aminonaphthalene1,3,5-trisulfonic acid), C10H9NO9S3, Mr 383.36, and its salts are readily soluble in water. Alkali fusion (65 % NaOH, 220℃) forms 2-amino-5- hydroxynaphthalene-1,7-disulfonic acid. Desulfonation to give 2-aminonaphthalene-5,7-disulfonic acid occurs on heating with dilute sulfuric acid. Diazotization and treatment with sodium carbonate yield the diazo oxide of 2-diazo-1- hydroxynaphthalene-5,7-disulfonic acid.6-???????-1,3,5-????? ?? ?? ? ???
