Usage

Description

Disodium 5-[(2,5-dichloro-4-sulphonatophenyl)azo]salicylate is a synthetic azo dye characterized by its dark yellow to dark red color. It exhibits solubility in water, with yellow coloration, and moderate solubility in ethanol, displaying a greenish hue. When dissolved in concentrated sulfuric acid, the dye appears orange to red, turning light green upon dilution. In concentrated nitric acid, it exhibits a titian color. The addition of concentrated hydrochloric acid to its aqueous solution results in a greenish hue, while the introduction of concentrated sodium hydroxide solution yields an orange color.
