7-((((5-hydroxy-6-(phenylazo)-7-sulfo-2- naphthalenyl)amino)carbonyl)amino)-, disodium salt ; 2-Naphthalenesulfonic acid, 3-(2-(4-(acetylamino)phenyl)diazenyl)-4- hydroxy-7-((((5-hydroxy-6-(2-phenyldiazenyl)-7-sulfo-2-naphthalenyl)amino)carbonyl)amino)-, sodium salt (1:2) . Water-soluble of Direct red 23 (CAS NO.3441-14-3) is medium and water solution was bright red. Its solution add dilute sulfuric acid slowed the blue, add concentrated hydrochloric acid produces a red wine sediment, plus concentrated alkali turn red orange brown. Slightly soluble in ethanol, orange, and do not dissolve in acetone. In concentrated sulfuric acid was in the red to magenta, orange, diluted turn brown; in concentrated nitric acid has orange-yellow precipitate produced; do not dissolve in concentrated alkali; soluble in concentrated ammonia was bright red. Copper ions when relying stained darker shade, shade no change in case of iron.
