8-Anilinonaphthalene-l-sulfonic acid ammonium salt

Anilinonaphthalene-l-sulfonic Acid Ammonium Salt Reagent... 

Dipping solution Dissolve 100 mg of 8-anilinonaphthalene-l-sulfonic acid ammonium salt in a mixture of 40 ml caustic soda solution (c = 0.1 mol/1) and 57 ml of an aqueous solution containing 21 g citric acid monohydrate and 8 g sodium hydroxide per hter. 

Spray solution Dissolve 100 mg of 8-anilinonaphthalene-l-sulfonic acid ammonium salt in 100 ml water [1]. 

Anilinonaphthalene-l-sulfonic acid ammonium salt, which scarcely fluoresces in aqueous solution, is stimulated to intense fluorescence by long-wavelength UV light (A = 365 run) if it is dissolved in nonpolar solvents or adsorptively bound to nonpolar molecular regions [3].
