Usage

Description

Disodium 5-[[4'-[[2,4-dihydroxy-3-[(4-sulphonatophenyl)azo]phenyl]azo][1,1'-biphenyl]-4-yl]azo]salicylate is a complex organic compound with a unique molecular structure. It is characterized by its brown color and solubility properties, being soluble in water for a yellow-brown color and slightly soluble in soluble fiber elements. It is insoluble in other organic solvents. disodium 5-[[4'-[[2,4-dihydroxy-3-[(4-sulphonatophenyl)azo]phenyl]azo][1,1'-biphenyl]-4-yl]azo]salicylate exhibits a color change when exposed to strong sulfuric acid, turning red light purple, and then yellow light brown upon dilution. When the dye solution is mixed with strong hydrochloric acid, it results in a yellow-brown precipitation, and the addition of a thick hydrogen oxidation solution changes the color from orange to red.
